Antimatter
Antimatter is literally matter which is the inverse or opposite of matter; particles which have charges opposite of regular matter.
Antimatter was first predicted by P.A.M. Dirac in his theory of quantum mechanics in 1928. Antiparticles were found soon after by Carl Anderson. Since then, research centers such as CERN and Fermilab produce antimatter particles on a daily basis. CERN uses a Proton Synchrotron machine to accelerate protons and then they inject them into the Antiproton Decelerator - a gigantic circular machine with a diameter of 18 km. Here the protons are smashed into a copper or iridium block of metal. The abrupt stop from such an incredible speed (about the speed of light) results in an enormous amount of energy released into a small volume, resulting in extreme temperatures greater than 10,000,000,000,000 Celsius. This enormous amount of heat and energy results in the spontaneous creation of matter-antimatter particles.
When antimatter comes in contact with regular matter - earth, air, whatever - it annihilates immediately in a 100% efficient reaction. A popular misconception is that this antimatter-matter reaction will someday allow antimatter for use as a source of fuel, or power source. Unfortunately, this is an impossible reality. Since antimatter is not found anywhere on Earth naturally (obviously), it must be created. With the equation E=mc2, it is IMPOSSIBLE to have a net gain of matter: the energy required running the accelerators would ALWAYS be more than the energy antimatter produced.
It's true that a quarter gram of antimatter has as much power as the nuclear bomb dropped on Hiroshima. This raises concern as to whether it could eventually be yielded as a terrorist device. Fortunately, it is IMPOSSIBLE to collect and store antimatter at this great of a density, and even if it were possible, with the current technology it would take billions and billions of years to yield that much. In fact, if CERN were to have kept all of the antimatter it ever produced; it would be enough to power a light bulb for about three seconds. Anyways, even with these things aside, it's completely impractical considering how much time, money, and energy is required to create antimatter.

Antiquitech
Antiquitech -
1. A method of generating electricity through architectural means. Usually using magnets, geometry or water to gather static electricity or radio-waves.
2. Ancient highly advanced technology which was lost for an extended period of time.
Origin: A combination of Latin antiquus, anticus ‘former, ancient’, from ante ‘before’. And Greek, ‘systematic treatment’, tekhnē ‘art.

Antimatter
Antimatter in matter composed of the analogous antiparticles to ordinary matter. Physicists believe symmetry breakdown at the most fundamental levels after the Big Bang resulted in our universe where matter predominates and anti-matter is all but non-existant.
Anti-hydrogen consists of an anti-electron aka Positron, orbiting an Antiproton. Truly miniscule amounts of Anti-hydrogen (a few atoms) have been made in the largest accelerator laboratories.
When reacted with ordinary matter anti-matter would indeed release enormous amounts of energy according to E=MC^2. However, much of this energy is carried away in neutrinos, which interact so slightly with anything at all, matter or antimatter, capturing the output of a M-AM reactor would present another huge hurdle.
However, it may not necessarily take more energy input than output. This is based on the misconception that the input to the accelerators is the same energy as released by the reaction. The energy released by a future M-AM reactor comes from annihilation, rather than being stored energy from the accelerator drive & containment. Most of the huge power requirements of accelerators goes into their magnetic confinement system. Suppose it becomes possible to re-arrange the quarks constituting normal matter into the configuration of antimatter much more efficiently. This is a big science fiction IF, by the way. Thus if a “matter inverter” were to function reasonably efficiently, the downstream M-AM reactor would see a net gain.
One possibility would be to base the “matter inverter” on a hypothetical Bussard Ramjet. This would be a magnetic or electrostatic “scoop” that collects interstellar hydrogen to power a hypothetical interstellar spacecraft at relativistic speeds. An accelerator might not be needed, as the hydrogen & whatever other atoms are out there would be running into the craft at near-light speed already. Although the Bussard scoop field(s) would probably use a lot of power in its own right.
Remember and be warned, when one extrapolates science far enough beyond the frontiers of present knowledge, it becomes largely indistinguishable from science fiction!

Antimatter Dimensions
A clicker game based on creating antimatter and using it to buy antimatter dimensions that create more antimatter and more dimensions. Eventually you can start buying galaxies and shiz until you reach 1e308 antimatter, which causes the Big Crunch. Keep doing this and eventually you can break the limit and unlock a ton of cool shiz.

Antimate
A bad friend, someone stabbing you in the back in public, highlighting negative sides about your character or just a douche.
On IRC.
#1: THERES PORN ON THAT LINK YOU GAVE ME
#2: So?
#3: Some people have problems with intimacy
#1: I googled that word, intimate or whatever
#2: You didn't know what intimate means?
Person #2 would be the Antimate in this case, highlighting the fact that #1 did not know the meaning of intimacy.

dead drop
A dead drop is a location used to secretly pass items between two people, without requiring them to meet.
Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.
A common place is to duct tape the item to the underside of a toilet cover in a public restroom.
A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.

"The dead drop is the restroom toilet at the Gulf station at the corner of Commercial Ave. and Georges Rd."

No Surprises Wedding
A "No Surprises Wedding," or NSW, is a wedding invitation designation that tells attendees that there can be no unplanned announcements, engagements, events or speeches at the wedding - all actions must be pre-approved by the couple. Anyone who performs an unapproved "surprise" will be asked to leave the wedding early.
This designation comes from Reddit, where so many stories of bad wedding behavior indicated a need to communicate expectations for the wedding behavior of attendees.

You are cordially invited to the nuptials of Brian and Tom on October 31 at noon.
Please note that this wedding is child-free (under 10) and a No Surprises Wedding (NSW). Reach out to wedding planner Sami Smith to request approvals or exceptions; please note that exceptions will be rare. Limited child care for under-10s will be available. All approvals will be noted and included in planning. Unapproved, or surprise exceptions, will result in guests being asked to leave.

EBK
EBK stands for "Elite Ball Knowledge." 1 In internet slang, "ball knowledge" originally referred to a deep understanding of football/soccer or basketball, but it has evolved into a broader term for having a highly sophisticated, deep, or niche understanding of any specific topic (such as music, movies, or subcultures).

Blexas
Texas is categorized as a swing state in presidential elections, but has voted for Republicans more times than for Democrats in recent history. As such, as demographics change political alignments, some Democrats believe that Texas will vote blue, or Democratic, due to their Hispanic and African American voters, who often align themselves with the Democratic Party's liberal wing.
Blexas has been cited as possible in the upcoming decades, but only if Democrats continue to win the Hispanic vote in bigger margins.
