"I'm a virgin."
Most girls can tell by the way I act that I'm clearly not. I've actually been asked this question quite a few times, and accused of being a man-wh0re several times, so that is usually my go-to and it works for me. Makes them wonder. When they say shut up! No, you're not! I just argue with them until they're tired.
Just this Sunday I was on a double date type thing (went into it kinda blindly), one of my plates wanted to drink but had her girlfriend so we hooked them up with one of my chicks male friends. So it was us 4. Home boy kinda started bragging about the chicks he's banged, and then the girls kinda jumped in. I sat there, quiet for a moment, and waited for the discussion to end, and then said "Oh, so I guess I'm the only virgin here huh?" Everyone knew I was full of sh!t, but then my plate proudly said.. "No he's not. I know that for a FACT" with a cute little face. I was so proud of her, I had to give her a that-a-girl right on the spot.
But yeah man. Just say something confusing, misleading, or just don't tell. I like Roscos "More than one, but less than 200". Might have to try that. I think one time when I was drunk I told a girl "One billion" very sarcastically. You kinda just get the same results every time.. "You're so full of sh!t!, tell me!" It doesn't really matter what you say honestly, just don't tell them the truth. :]
