Shaddap 

Pronounced with excessive exaggeration of the second "a", as in example 1. Shaddap is used to tell somebody to shut up without sounding overly serious. It can also be used pre-emptively, as in example 2. The crowning usage of shaddap however is as an unexpected end to a phrase, particularly when used to imply that somebody had said something extremely stupid.

1. "Shaddaaaaaaaaaaaap."

2. "I know what you're going to say, and I'm telling you, shaddap."

3. "How much more does a hard drive weigh when full?"
"Oh it weighs about shaddaaaap."

shaddap 

What you grumblingly mutter under your breath when a self-proclaimed rod-'n'-reel expert boastingly launches into one of his infamous "fish stories", and your tall-tale-weary eardrums sorely wish dat he would just quit flappin' his gums for once.

Bombastic angler: I **fish**, therefore I **lie**!
Listener: Aw, shaddap...!

shaddap you face 

(v.) To make quiet, phrase used by Italians, and made popular by a 1983 song by Joe Dolce, who had a very bad Italian accent.

"What you say to me? SHADDAP YOU FACE!" *slap*


What's-a matter you, hey, gotta no respect
What-a you t'ink you do, why you look-a so sad
It's-a not so bad, it's-a nice-a place
Ah, shaddap you face*



*candidate for worst song ever.

This is the reply one should use when some idiot attempts to tell you how you should do something you already deal with on a regular basis and that they have never experianced and know nothing about.

Mr. Knowitall was once again getting on everyones nerves by telling them how they should complete the job when one individual shut him up by blurting out, "shaddafuckup".
