I'm a super slick on the spot liar. I come up with really intricate stuff that requires friends going along with it. It's all kinds of fun.
One night a group of us are at Q's, this club, and Micah explains Shirpas to us. Not the guides in the Himilayas that tell you what to do, but when your friend is about to make a bad drunk hookup decision and you slip the word shirpa into the conversation - so you're acting like a dating guide and warning them. So my roomie is stuck talking to this guy who looks like an accountant who's never gotten laid before and I walk up and say, "omg! You won't believe who's here!! Shirpa!" We run off, but later we run into the guy and I introduce our friend Dave as Shirpa and tell the guy he just got back from Malaysia. Fortunately Dave figured it out and went right along with the lie. It was the joke of the night.
So, my point is, you shoulda let the girls believe you were a bigshot and not sold your friend out.
