Nastrogen

Someone so butt ugly or (nastro), usually of the opposite sex that you wouldn't even poke them with a 10 foot pole for a million US dollars

Damn that bitch is DIRT nastrogen!

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.

Nitrogen Monoxide 

when you type 'no' all-caps in your tiktok caption and put it on tts

your caption: "OH HELL NO LMAO"
tts: "OH HELL NITROGEN MONOXIDE LMAO"

Nitrogeno 

The way every Italian reacts to seeing the word "Nitrogen" because apparently in 2021 no non-chemist Italian whatsoever understood that "Nitrogen" is actually "Azoto" in italian and not "Nitrogeno".

Italian non-chemist: HA APPENA MESSO IL DITO NEL NITROGENO LIQUIDO, QUESTO È PAZZO
Italian chemist: SI CHIAMA AZOTO. Giuro che se dici un'altra volta "Nitrogeno" ti ammazzo.

Smart man's liquid nitrogen 

Smart man's liquid nitrogen is dry ice mixed with 1,1-Difluoroethane. The boiling point of 1,1-difluoroethane is -11.29°F (-24.05°C) while it's melting point is -178.6°F (-117°C). The sublimation point (the point at which a substance sublimes, or goes from a solid directly to a gas) of dry ice (solid carbon dioxide) is -109.2°F (-78.46°C). Smart man's liquid nitrogen stays at around -78°C as long as you keep supplying more dry ice. Then the dry ice runs out and it heats up until it reaches -25°C where it becomes homeless man's liquid nitrogen. Then the 1,1-Difluroethane (can be found in computer duster) slowly boils away until it becomes gaseous 1,1-Difluoroethane. You can keep chemical reactions cool with smart man's liquid nitrogen and once it becomes homeless man's liquid nitrogen, you can use a funnel and a plastic soda bottle to store the liquid difluoroethane under pressure and label it and put it in the lab freezer.

I kept my chemical reaction extra cool with smart man's liquid nitrogen.

Helium Nitrogen Tantalum Iodine 

Another way to say Hentai with periodic table elements. Also another was to be called smart-ass by your friends.

(insert hentai orgy)

Albie: What does Helium Nitrogen Tantalum Iodine mean?
Mexie: It means fucking HENTAI so go watch it
Albie: Sure.

Nitrogen 

Seventh element on the periodic table. Makes about 78% of earth's atmosphere. Used in stuff like amonia and plant fertilizers, and found in proteins, so you need it.

Nitroglycerin, a major explosive, contains nitrogen.
