These are the initials of a particular person, more specifically of a girl. This person is the definition of dumb bitch and is probably the biggest and simultaneously the worst whore out there. Word to the wise to the go out with this girl because she will definitely cheat as she has done to her current boyfriend more times than you can count on your fingers. Wouldn't think the guy would stick around but he did; he says it's because of love but really it's because he's a pussy and a bitch. Believes he can't get any other girl and thinks that L.A.M is the best for him HA. Use this describe a girl that is being an absolute cunt and bitch and if she's cheating on her boyfriend non-stop.
Hey, is that L.A.M over there?
Yooo, his gf is totally a L.A.M.
