US Slang Expressions

[spacechaser2000]

Delurking for the moment to add:

"Spit'n in the wind" means a hopeless feat.

"He/she ripped me a new one" or being told off or being yelled at 
(the expression implies something crude happening to one's bottom).

Any sentence that ends in a preposition (see above example)which is 
a common mid-western thing.

I don't know if this is unique to the US but "pulling my/his/her/its 
leg" implies that someone is joking.

I've heard "popped the cork" used to describe someone with an 
explosive temper.

Being "knee deep in sh**" means you're in a whole lot of trouble.

When feeling "down in the dumps" or "feeling blue" means you're sad 
or depressed.

That's all I could come up with for the moment.
