yughhhh

Pronunciation: yu-ghhhh (the "ghhhh" sound is made with a sufficient amount of phlegm)

Not truly a word but more of an expression, yughhhh falls under the "yuk" category of sounds. Unlike the typical "yuk" which is universal for all human use "yughhhh" is exclusive to dirtbags, scumbags, or generally nasty people. That being said, "yughhhh" is a sound to express a truly disgusting act which even disgusts a dirtbag.

Me: I ate out a squirrel yesterday!
Matt: yughhhh

Clare: Worshipping the devil is the best thing ever
Matt: yughhhh

number onee

"number onee" is a phrase rather than word. It is the international sign of approval amongst dirtbags, scumbags, and disgusting people. When you call someone "number onee" this should be accompanied by a raised arm, closed fist, with your index finger pointed at the person and wagged at them. Now, the phrase does not always need to be accompanied by the gesture and the gesture does not need the phrase to get the point across; they are best used together but are just as sufficiently understood seperatly.

(Ale hits on 13 year old girl; he is 26)
Matt: You're number onee
Ale: Omg thanks man!

(Matt is getting a bj in the woods, Sammy passed by, they make eye contact, Sammy gives Matt the "number onee" gesture, Matt cries one tear of happiness)
