mouthassjackery 

1. Talking about something or someone in a positive light, when in reality, the words coming out of your mouth are pure fiction.

2. Talking about something you don't know anything about while trying to present the illusion you are educated on the subject.

3. The act of saying absolutely ridiculous shit.

example 1:
Joe: George Bush was the best president the United States ever had!

Jack: Imma punch you in your dumb face if you don't stop that mouthassjackery.

example 2:
Vince Offer for the SlapChop:
... This thing, this tuna looks boring. Stop having a boring tuna, stop having a boring life. Add this tuna putting it in like this now you’re going to have a nice, tuna, salad. Look at this you’re gonna have an exciting life now.

TV Viewer: LOL - good ole' Vince ... He is the master of mouthassjackery.

Chewbacca Mouthwash 

When one partner diarrheas into the others mouth. Then they proceed to gargle the diarrhea making the Chewbacca Wookie noise. After a thorough fresh poo tainting of the mouth they spit the liquefied fecal matter in to a sink.

(Note: Best if done after eating Chinese or Mexican foods.)

Ricky said to her "Your breathe smells like straight Chewbacca Mouthwash girl!"
