I dont know about the 3-generations-same-bloodline-definition listed here, but nailing 3 different women in a 24 hour period is a trifecta.

So I did happy hour with LeAnne. Railed her in the parking lot, then drove to the Cafe to meet my girlfriend. Well, she wasn't there yet, but her sister was. So I railed her in the banquet room. When she finally did show up, we just went home and went at it like spider monkeys. It was the best 7 hours ever.
