look up any word, like dirty sanchez:
 
1.
noun.
Irish slang.
A person who runs off at the mouth, and is completely full of shit.
Actually, the phrase is a combination of two Irish slang words scutter meaning diarhea, and gobshite, a person who doesn't know what they're talking about, but talks anyway.
Would you ever shut up, ya scutterin' gobshite ?
