The one that James described--"the house no one wants to be in". Okay, y'all, again I am not talking about one of the smaller groups or one that's less visible or isn't full of queens. I'm talking about the house you get on some (not all) campuses that is full of skanks or known for vicious hazing or has so little spirit that they--all at once--have by far the lowest GPA, refuse to enter Greek Week or intramurals, and won't contribute to anyone else's philanthropies with bucks or bodies.
You guys know what I mean--it's the group that the PNMs know after first parties (even if they went into rush with a totally open mind) that they don't want.
And right now I don't know of a group like that on any particular campus but I have seen several in the past.
