A rapidly spreading meme that originally came from CSI:Miami. Horatio would say a sarcastic/corny/funny/stupid line and then put on his sunglasses. Right after this, the theme song for the show would blare "YEAAAAAAHHHHHH!!!!". This is now used to signify something funny or corny yet to come
"These charity people keep calling!" "It Looks like" *Puts on Sunglasses* "They give charity a bad name" YEAAAHHHHH!!!
