That's a great question...
I can think of some that I'd rather not post, because they're culturally context based...
the only other ones I can think of are pretty lame, hehe.
like how "bad" itself can mean good....
"bitchin'"
How about this?
In Shakespeare's time, the phrase "to die" was a slang term meaning "to have an orgasm..."
Nice turn of phrase, there... :whistle:
