cunton-mouth 

the subsequent nasty sensation left lingering in one's mouth after performing cunnilingus (frankly I don't care whether it's experienced by male or female). counterpart: cockon-mouth.

Male 1: "Yeah so there I was balls deep and I thought, why not go down on her. Big mistake!"

Male 2: "Dead skunk?"

Male 1: "Totally, I almost puked. I must have brushed my tongue for 5 minuntes and still had cunton-mouth. And on top of that the bitch rolled over and went to sleep."

Male 2: "What a cunnilingrate!"

Macho Mouth

To keep attacking with words too a "some-one” in an inappropriate manner until that “one” gets irritated enough to get Macho with you.

Manipulating ones disposition from one brief moment to the next in a short period of time.

-To goad one into a mode of anger and aggression.
-To get underneath ones skin to attain a sense of control.

Cool and collective Tom was playing pool with Dumb-ass Dick and Dumb-ass Dick started too rudely and obnoxiously criticize Tom’s game during his shooting.

To get Macho’ed the reaction would be.

To be in a calm and cool manner in one moment and then suddenly manipulated too an agitated and hot-tempered manner after being attacked by a Macho Mouth.

World of mouth 

This is an elaboration of the expression "word of mouth" in which something (usually a product or service) is spoken about either favourably or in a good light. This phrase has been introduced to reflect the impact of social media which now allows these comments to go viral, and quite simply become world of mouth rather than word of mouth.

The latest Harry Potter film has received good reviews through world of mouth marketing!
