groovemonger 

A person who readily dedicates their occupational existence to the sale and resale of anything but a good tune (groove). Thus, "groovemonger" is an oxymoronic term that is rather general in its persuation (meaning).

I think I'll visit the groovemonger because he has nothing to offer me but his lack of identity - and I like that.

groovemongrel 

Something that smells and stinks like butt

Man look at that dirty groovemongrel, no wonder why it has no friends.
