Apparently, I almost own this keyword so I might as well define it fully.

A lollygash is the cut you get on your tongue when you're trying to find out how many licks it takes to get to the center of a tootsie roll tootsie pop, and the candy develops a nasty, sharp, edge.

Lollygash is also an (arguably horrendous) genre of music/mash up in which porn sound tracks are mixed with electronica.
