gravelcruncher 

A peeping tom. Someone who might tread on the gravel next to say, a shower or bedroom window.

I was in the shower and thought I heard a gravelcruncher outside the window.

Gravel Cruncher 

Gravel Cruncher - someone who has horribly crooked teeth and doesn't care to fix them. Someone who smokes crack excessively, as a result loses teeth Can also be considered a "gravel cruncher".

I would hook up with dude, if his teeth weren't fighting for position in his mouth. What a gravel cruncher!
