A way in which a user smokes marijuana. A bottle (preferably Aquafina) is used in which a socket wrench cap is used as the bowl where the cap is. A carb is then burnt into the bottle at the bottom for draining purposes. then put a bowl in the hole in the cap and fill the bottle up with water (and put weed in the bowl). Ignite the marijuana and unplug the hole at the bottom of the bottle. Asthe water drains out the smoke should be pulled into the chamber. When all teh water has been drained out, take off the cap and suck in the compressed smoke.

Get Bummed. Can be used to mean "It's your own fault, get over it" (Ex. Student: "The dog ate my homework!" Teacher: "GB.") or "this isn't going to be good." (Ex. I am going to totally GB on this test. I didn't study at all!)

This word was created by a wonderful teacher at SLVHS.
You didn't hear what GB means? I've already explained it twice, so just GB.
