Motormouth 

1. A person who talks too fast and too much. The fast talker won't wait for a break in the conversation, they just overtalk everyone else.
2. A bad actress who rushes her lines because she's afraid of forgetting them.

Don't invite Mia to the party, she's an obnoxious motormouth.

Motormouth 

is a reality show on VH1 which showcases people unknowingly being taped in their cars while singing a song. It began airing October 26, 2004.

The skits would end when the victim stopped and the cast went in and Zane would say to them, "You've been Motormouth-ed".

in-flight motormouth

making the mistake of 'being too friendly' with ones' seat partner on an airplane flight, only to realize to your horror; the person is unable to SHUT THE FUCK UP!!

often, these are people with some kind of flying fear, their method of dealing is to talk incessantly!! IF the person is BORING (frequently the case!) it can drive one crazy! -one has to be out and out rude, to be allowed entry into ones' own personal world!

i use two methods for dealing: (1) headphones/ipod & (2) faking like i've fallen asleep! -books are good too, if you get 'into' the book immediately!! and act totally enraptured, which you CAN be, if you have the right book!

welcome to shit city! did you have a nice flight? fine, except for the in-flight motormouth!

an in-flight motormouth tortured me all the way to poop town!!

we experienced terrible turbulence which help distract my in-flight motor mouth!
