Taken from the hit sitcom "Family Guy," this phrase can be said to anybody who either kills a joke, makes an uncalled for comment, or otherwise just needs to be ridiculed spontaneously.
Steve: "I think that octoberfest might be the best beer ever."
Bobby: "I agree"
Jeff: "I think beer is disgusting no matter what it is."
Steve to Jeff: "Shut up, Meg."
Bobby: "I agree"
Jeff: "I think beer is disgusting no matter what it is."
