What's your favorite?
What region are you from if it's familiar to you?
If you've heard it elsewhere, other than in that region, where was it?
My favorite is "She's slippy, you're sliding down." from Mysterious Ways.
I'm originally from Pittsburgh, Pennsylvania. Mysterious Ways first got me into U2 back when I was a 15 year old dork, and when I heard them use the term "slippy," I felt they knew where I was coming from.
If you've heard it elsewhere, other than in that region ("Born Slippy" by Underworld doesn't count) where was that?
