Green Beret 

When you're fingering someone and stealthily pick your nose, then continue with the booger finger(s) without cleaning it off.

I had a cold so I slipped her the green beret.

Green Monster 

3 foot green lexan water bong with a slide bowl (rip ~ 2001)

occasionally paired with the Liberty Bowl to extend bowl life

challenging hit for some, as it held too little water to provide chilly nice but a very useful tool for those who practiced with it often

also see: Malice Green Monster

"Green Monster?"
"Fuck that...Malice Green Monster!"
"duuuuud"
"pussy!"
"FINE...pack that shit up, asshole!"

Green Giant

The word used to describe a "joke" that was so bad that no one laughs. Bad jokes such as these generally cause about 10 seconds of awkward silence which can be filled by saying the words "Green Giant" in the same way as it is said on the advert for Green Giant sweetcorn.

Originated on a school trip to Berlin in which the worse joke ever told was about a green giant. Another term that describes the same thing is lead e.g. a lead joke.

Tanc: *Tells and awful joke"

*Awkard Silence/Tumbleweed"

Charlie: Green Giant...
