Mouthsage 

A blow job, to get your dick sucked. Word invented Tuesday, November 4th, 2009. Mouthsage can be used in many ways, think of a way to humiliate your friends, "where are you going man off to give a mouthsage?". "I hear he's off giving mouthsage's out back at the glory hole."

Hey babe give me a mouthsage?
Micky-Mouth gave Donald-Dick a mouthsage.

Mouthquake 

An intense amount of vibratory sensations in the mouth brought upon by many things including pop rocks & pop &/or alcohol, vibrators in the mouth, or certain bitchslaps.

I was eating pop-rocks and drinking rum lemonade and had a 7.2 mouthquake.

That pornstar is totally having a mouthquake right now.
