I had a girl use this on me.
I was skiing with friends and this random chick tagged along with us. I thought I was going to have to coach that day and left my civies at home, so I had to borrow some gear from a friend. He's a pretty big guy and the stuff, especially the ski pants were huge on me. I was definitely going for the serious baggy look that day.
Riding up the lift with the random chick, I made a comment that the pants were so big that two of me could fit in them. The girl says "well, you can get into my pants anytime you want." I looked over at her and she says, "...seriously". She was definitely smokin, and I was pretty much floored.
Here's where NS is going to crap all over me. I told her "thanks, but my wife and kids would probably be bummed". Thankfully I did all of my pillaging prior to marriage. No interest in throwing it all away, regardless of how good the pickup line is. Truth.
