It really won't help you much. We make them up. Just try to pay attention.

There are a number of slang dictionaries on the web. One problem is that they list a number of slang words and terms that you would almost never hear. It's simply too much. Here are a few phrases: "Out to lunch" - crazy. "Screwed" (as in "We're really screwed") = in a bad situation, cheated. "Rip off" - steal; a "ripoff" is either something which was stolen or something where you pay too much money. "Haul ass" - move fast (usually away from the current spot). "Wasted" - high on drugs or alcohol "Pissed" - (American) angry; (British) drunk "Three sheets to the wind" - drunk "Dressed to the nines" - dressed very well. "Have a cow" - (give birth to a cow) = get overly exited or panicky about something. "Chill out" - calm down "Wound up" - very tense, nervous "Wired" - Very tense due to coffee or high on some drug. "Buzz kill" - something that kills a good time. "Buzzed" - slightly drunk or high on drugs. "Dragging" - very tired.
