Homeless Man's Liquid Nitrogen

It's liquid DFE(1,1,-difluoroethane) that's commonly sold in certain stores as computer duster. It is used when neither dry ice or liquid nitrogen is obtainable. It's usually used for science, to freeze things, or just for fun cooling thermometers, water, or some insects. The computer duster can is used for dusting off the dust from computers using the DFE gas. however, when turned upside-down, it provides a frostbite causing super-cold liquid that's -25 degrees Celsius(-12 degrees Fahrenheit) or colder. It is sometimes(very very rarely) used to try to liquefy formaldehyde or other gases, but due to the toxicity of these gases, a gas mask is recommended. It can liquefy butane, a far less toxic, but highly flammable gas. Getting Homeless man's liquid nitrogen on skin can be deadly, as frostbite can occur. It's a cryogenic liquid.
Dude, I just froze some cockroaches, a container of water, and liquefied a gas using Homeless man's liquid nitrogen.

nitrous bong rip 

Nitrous Bong Rips: an elusive phenomenon that has lurked in the shadows for century upon century, looming just around the corner, waiting for its most opportune moment to attack society’s mainstream like a swarm of bees enveloping its unfortunate prey in unison. The NBR perhaps represents the most creative and progressive attempt to take drug users/abusers mundane activities to a never-before-expected level. A synthesis of the relaxing marijuana smoke with the chilly nitrous hit that induces half a minute of incapacitated euphoria has proved to be a magical combination: one that incites a series of sensations only understood by another NRB user.

The history is largely unknown, but its following of cultish proportions has become a topic of interest on its own. Nitrous oxide is a gas used to make whipped cream, and can be purchased in packages of several cartridges. Though illegal to use as an inhalant, nitrous oxide (often called “whippits”) is utilized by many young people, especially adolescents with limited incomes, to achieve a cheap and quick high. A balloon is inflated with a nitrous cartridge, and is fastened to the slide of an already-lit bong. The hit is inhaled as the balloon is released, allowing the individual to experience a bong rip and a nitrous hit simultaneously.
"Yo dude, let's go back to the apartment and take some nitrous bong rips and then eat some hot dogs!

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.
