An abbreviated form of molester moustache. Refers to the thinned-out hair clumpings grown by testosterone-challenged pedophiles and other shady sorts.
"Did you see the molesterstache on the guy driving that van? I bet he's hiding a clown suit in the back."

A gnarly, unkept moustache typically sported by child molesters, hillbillies, and convicted fellons.
The camp counselor sporting the molester stache was not introduced to the parents on orientation day, for fear that they would object to his being near their children.
