masterblathering 

Excited, pointless and always somehow self-referential verbal-diarrhea. (See ANY Tarantino interview.)

Not an example of usage, examples of actual masterblathering:

"You don't have to tell me how cool I am, listen to ME tell you how cool I am!"

"Did you see me at Madison's party? Everybody was waiting for me to do something cool, I know, but I made them wait until Madison was right next to me. Did you see it? I was SO AWESOME, dude!"

"So I watched this movie once called "City on Fire" at the video store they let me work at and I thought "Shit, nobody's seen this! If I can get Harvey Keitel and that funny-looking guy from Fargo I can totally rip off my first movie!"

Manterboating

The placement of one's face, into the cleavage of a man's moobs, followed by the side-to-side shaking of the head accompanied with a motor-ing sound.

John made many trips to McDonalds on Friday; resulting in a hefty, yet delicious figure. Sarah was captivated by his rolls and decided manterboating his moobs at the pool the next day would be a hot idea.

Masterblader

The Masterblader whistled twice to signal the jammers to start twenty feet behind the pack.

Masterboy 

A german eurodance group very popular in 90's in Europe, Oceania and South America.

Masterboy marks the end of good dance music. All things released after 1995 of this genre sucks afterall.
