chastity tube 

n.

A rigid (or semi-rigid) enclosed tube that slides over the penis, interlocking with a rigid ring that slides over both the penis and testicles. There is usually a hole at the tip for urine to pass through to allow for long term wear. Once locked in place, the tube prevents the wearer from obtaining an erection or receiving traditional male genital stimulation.

Becky: It bothers me when my cuck husband Mike gets a boner. I'm never going to touch it so it's pointless.

Veronica: I know, like as if any girl would want to touch or see THAT. It's like tiny and stuff.

Mandy: Why don't you get a chastity tube for him?

Veronica: Like, what's that and stuff?

Mandy: There's a ring that goes around his junk and a tube that covers

his little pee pee. When you connect them together, he can't get another useless stiffy.

Becky: That sounds perfect!

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.

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."
