Over-the-pants-rim-job. Much cleaner than the traditional rim job and definitely tastier.

Over The Pants Rim Job (OTPRJ) 

When a girl or guy who, with their tongue rubs in a circular motion around someone else's sphincter over the pants. First discovered at 18 Brock Place.

Hey Jordan do you want to come to my house and give me a Over The Pants Rim Job (OTPRJ), with my khakis on.

P.S. You suck at Smash Bros.
