Also a huge one for me is when girls are super into their own boobs. Fondling themselves, wearing flashy clothing that shows them off, excessive cleavage and teasing, getting off on playing with her own nipples, Intentionally bouncing in your face. A girl who has some weapons and knows how to use them.
I'm not as much of a fan of "just has big boobs" on a character I guess. It's more fun when they're proud of their assets.
