A challenge when singing karaoke for a party other than the singer/karaokeist, typically the crowd or the DJ, to pick the song. Thus, a metalhead who typically sings metal may have to sing a chick song. Often, karaoke challenges are reciprocal.

Get the Jell Jell Beanmug. Robert is at it again. Every time he goes to a gay event, a flock of gay men gravitates to him. He gets dick, a blow job & ass almost every night. He’s known as a professional battymanist.
