A "Gruntboy" is a rugged and exciting young man from the North East of England who is outrageously foul-mouthed and toilet-humoured on the outside but is surprisingly sweet, tender and devoted when he becomes your precious lover man.
My boyfriend is such a cheeky Gruntboy.

A woman with facial hair and a clitoris long enough to be mistaken for an extremely small penis.
She was born a bit of a Gruntboy, but I think she is contemplating surgery.
