NMR tube

An NMR tube is a tube used in NMR Spectroscopy (used to detect molecule structures depending on peaks on a graph). Cleaning it usually uses acetone or dichloromethane and getting rid of it involves vacuum and maybe IR lamp. Organic chemists sometimes send samples to an NMR lab to get it back with the graph and detect if they got their product.

Steve: I cleaned the NMR tube with acetone.

Rusty inner tube

A rusty inner tube is a sexual act in which you preform a rim job on a persons butt hole immediately after they go poop, before they wipe.

I licked sally's asshole after she pooped and it looked like a rusty inner tube.

down the tube

Another way of saying that something is really going to pot -- when you say such-and-such is going down the tube, it is spiraling downhill extremely rapidly.

Man this drone flight is really going down the tube...O FUCK, There's a tree!!! (*CRASH!!!*)

That woman's performance on American Idol started to go down the tube when she forgot a critical lyric to the song she was performing.

Blowin’ a tube

Blowin a tube is like when you have a lot of milk or ice cream and you’re lactose intolerant and you run to the bathroom and blow the tube clean out. Your tummy can’t handle it, and you blow a tube.

Hey Tony, I had way too much mozzarella last night and was really blowin’ a tube. I had some explosive diarrhea!

hippy tube

n. A home-made device, usually crafted out of fabric softener sheets, a spent toilet paper roll and a rubber band. The hippy tube will greatly reduce the average pot-smokers risk of being caught by any type of authority figure. If 8 out of 9 pot-smokers use the Hippy Tube during 90% of all cannibus consumption, scent of burnt reefer will be reduced by up to 3x, where x is number of weeds smoked. Also more commonly referred to as a "hippy stick" in the South.

"Donnie, will you please include the hippy tube when you pass me that blunt? Mom's in the kitchen and she already thinks your stoned off of numerous drugs."

boob tube

television. Negative connotation.

I see you're watching the boob tube again. Don't you think 6 hours of t.v. watching is enough for one day?
