Oh my gosh, I thought my friends and I were the only ones that did this :)

I'm always either Kristin or Bridget

If the guy is sketchy, I say that my names is Aubrey James or Wendy James.

Quinn Martindale

for those times when i feel like being Irish, it's Minerva O'Donnell.

If I get caught in a icky-guy situation I normally just use "Renee Myers". Simple. Plus, you know that boring names are always believable :p

Justin Case ;)

I don't give out a fake name. One night everyone gave the name of a sorority sister. It was funny.
