Here's an old classic from when me and Pocaroba had this same contest at the Wherehouse in Salem:
"She Came out in Chunks" by Broken Hope from their classic album The Bowels of Repugnance. Broken Hope is a goldmine for classic song titles, like "Chewed to Stubs", "Skin is In", and "Necro-fellatio". Good stuff, good stuff.
Metal guys must just stay up until all hours of the night coming up with song titles. I would be willing to bet that it is a title first, lyrics second sort of medium.
I love this feature all ready. This was a favorite game that we would play on slow nights at the Wherehizzity. Another was finding the most offensive metal album cover. That first song title was gold.
