1. When an MC is so horrible he or she is only worthy of performing a karaoke club 2. When you make a woman cum so hard she start to sing like she's in a karaoke.
1. John's lyrics are so bad he's only karaoke big, he'll never make it in the rap game. 2. Tyrone gave me this karaoke big orgasm I was singing his name so hard the neighbors heard me.
