Gonnaherpasyphilaids is actually one of my personal favorites. I find it to be an excellent all-purpose word basically meaning that the individual in question has a high likelihood of carrying one or more diseases of the naughty regions that are non-responsive to penicillin. This word came into usage during my sophomore year as a response to the choruses of “I’d do her” that accompanied almost any chick of even modestly attractive features. That is to say, “Yeah, you’d do her, but you’d probably end up with gonnaherpasyphilaids.” This term is still regularly in use.
