pfaf (and implicit alcohol reference)
Yeah, I have to drink* for this one. Especially the dress.

*For those who don't know me in RL, this is a reference to the "Raggedy Ann and Andy Drinking Game" @anthracite introduced me to. You watch a movie, preferably the eponymous one, and every time one of your kinks gets referenced on-screen... you drink. You drink _regardless_ of whether the specific instance on screen arouses you, or is even pleasant. (e.g., if you have a feeder fetish... you gotta drink for the egg contest in Cool Hand Luke, even though there's nothing sexy about it in the least)
So "I have to drink for this" is basically personal slang for "this is embarrassingly close to my kink territory."
