When one guy gives head to another. Giving fellatio.
Jim gave his boyfriend a mustache ride last night.

Get the mustache ride mug.
The act of a man's clean shaven face being ridden by a woman with a hairy bush in order to receive cunnalingus.

A mustache ride being performed on a man without a mustache.
My upper lip is chafed after that reverse mustache ride last night.
Get the reverse mustache ride mug.
