the girl in a pair who is a little less attractive than the other; every house party has one knock-out-of-your-league supermonster hottie that grew up in Barcelona but is here directing videos even though she’s only 21. If you go for her you will bomb. Go for the lamprey next to her and at the very least people will respect you for not being shallow. The lamphrey can be found next to her, and she is less hot.
person one: "Man, did you see Natalia? That girl is fiiiine."
person two: "Yeah, but you ought to go for her friend Jenny. She is the obvious lamphrey."
person one: "You know something, Dick? You are totally right. I am going to hit on the lamprey right now!"
