An abbreviation for "Too Young For Those Tits" Usually when you see a young/teen girl with massive tits that biologically shouldn't be as big as they are.
Me: Hey, did you see Stephanie? She's definitely TYFTT.
Friend: I know man, she's only 16 and has HUMONGOUS knockers. I'm not complaining though.
