Durr

An exclamatory word used to proclaim excitement, encapsulating the very essence of hype. Of the same general meaning has 'hell yea.' Functions similarly to a verbal dap up and is customarily preceded by the word 'fuckin' to amplify effect (Fuckin' DURR!).

“And you just know I had to eat it bro.”
“Fuckin’ durr dude. That’s what I’m talkin’ about.”
