look up any word, like tribbing:
 
1.
When a friend or mere acquaintance signs you up to sing a song at a karaoke bar, unbeknownst to you.
"I just went to this stupid place to honor my friend's 30th, but I totally got karaoke raped in the process."

Karaoke DJ's response to a bogus entry: "This bar does not support karaoke rape, if you're gonna cum- you cum willingly!"
