It's a WTFbomb.
*Beep*Beep*Beep*Beep*"WHAT THE FU-BLEEEEEEEAAAAAAAAAAARRRRRRRRRRRRRRRRRGHHHHHHHHHHHH!!!!! MUUUHUHAHHAHAHAAHAH! MUHAHAHAHAHAHAHAHAHAHHAAH!!!"
That's about what it sounds like. I forget what it's from, but just look up WTFbomb and you should find it instantly.

Beep sound is from CS, "WHAT THE forget" is from the Steve Mustache Show and I have no clue what the boom and laughter are from.
