I dont know how well this would flow with Lamda Chi but at my undergrad the Sig Taus wanted to make a shirt like that for all the close friends of the house that were girls. it would have said

Front: Rush Sig Tau?
Back: Would if I could

Personally, I don't like the "groupie" terminology... but that's just me :)

A bunch of the LX girlfriends at my old school made shirts that had "If I were a guy, I'd be a Lambda Chi". It was cute. The girls loved them, and the guys thought the shirts were cute.

Yeah, that's kind of why I have questions about the whole thing. I also can't see myself wearing a t-shirt with another organization's name/nickname on it, unless it's an event shirt or something of that nature. Different strokes, I suppose. :)
