Girls who conveniently forget they have boyfriends.
Then you find out they do and they're all embarrassed around you. Pretty annoying.
Especially when they have ample opportunity to slip it into the conversation but don't. At least she admitted she lead me on and apologised for it, still very irritationg though.
Surely any girls that do this can't be that committed to their boyfriends, otherwise they wouldn't be even the slightest bit interested in anyone else.
