Personally, I have a few of these names under my belt:
I was in a half-assed project called Alabama Cousinfuckers in my sophomore year of high school, followed by an attempt at one-man stoner doom called Krokodil (see the heroin alternative for the reasoning behind the name), I pitched in the name Cuntslaughter for a third group, and now I have ties to a band that accidentally named themselves after the Latin word for "sewer".
