Antipeen 

A penis so small, its actually stretching backwards through your ass all the way from here to Mars.
The existence of an antipeen would bring down the avegare penis size to about 4mm, as it would measure about -472 billion mm.
Guy 1: I wish the average penis size is 4mm.
TheMonkeysPaw: Granted, you now have an Antipeen.
Guy 2: That sucks, dude.

Antifreeze 

Any substance which is a solute that lowers the freezing point of a solvent. Water(Hydrogen oxide) is the usual solvent. The solute is usually sodium chloride, calcium chloride, ethylene glycol(toxic), propylene glycol(non-toxic, safe), 1,2-Butyleneglycol(nontoxic) glycerol(nontoxic), ethanol, and a tick protein called IAFGP. Ticks have a protein called IAFGP that is triggered during winter months, which protects them from the cold. The freezing point of the solution gets lowered. Freezing point depression is a colligative property.
I put propylene glycol antifreeze in my car and it resisted freezing in the winter. The dog accidentally drank some propylene glycol but turned out fine. If it would have been ethylene glycol, the dog would have died.

Antifreeze tick gene 

A gene that allows ticks to produce an antifreeze protein to resist frostbite and lower the freezing point of blood. The ticks have a protein called IAFGP that is triggered during winter months, which protects them from the cold. Mice that were injected with the protein were able to not get frostbite at subzero temperatures. They then genetically engineered the mice and breed them to have babies with the gene and they produced the antifreeze protein, IAFGP. The mice resists frostbite. One day, some humans could genetically engineer themselves with the antifreeze tick gene. That way, there's no more frostbite at subzero temperatures(below 32 degrees Fahrenheit, 0 degrees Celsius) until much lower temperatures(like 5 degrees Fahrenheit, -15 degrees Celsius or something). Eventually, the technology will be affordable to all.
Tyler: I just genetically engineered myself with the antifreeze tick gene. Now I don't have to worry about frostbite.

Antifreeze 

Antifreeze is that greenish yellow liquid your dad puts in the car. It's ethylene glycol. It keeps the car's cooling engine from freezing. It's done in cold places and it's a tradition that goes from generation to generation. Don't drink it though, or you'll die. It's sweet tasting, but deadly toxic if you drink it.
You: Dad? What's that yucky green stuff you're putting in the car?
Dad: That's antifreeze! Someday you'll follow in my footsteps and winter-proof your car engine.

antigender

This old white lady asked me what my gender was, so I glared at her and told her I was antigender. Take that you patriarchal sympathizing boomer.

Frothability 

The measure of an emotional and over zealous consumer in an upwardly charging market, also known as a bull market. It's characterized by rising asset prices, increased investor confidence, and favorable growth in the markets, bro.
The frothability was evident as over-zealous consumers eagerly engaged in bidding wars, driving property prices to unsustainable levels reminiscent of previous speculative bubbles.

pod person 

A person pretending to be something they aren't, or an impostor. This is inferred because of the old alien movies where alien pods appear on earth and the "pod people" dispose of the humans and slowly reproduce the bodies, pretending to be humans.
The pod person was pretending to be my father, but I knew that he was an alien when he acted differently than my father ever would have.

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.
