Taping oneself doing karaoke (Well or Poorly) for the purpose of posting it on a video sharing website to keep in contact with friends that are too far away to socialize with in person.
*E.g. friends at a different college / university or friends serving in the military.*
The videos are considered sociable challenges to friends and must be responded to in order to be a true karaoke-off.
Friend 1(on the phone): Hey bro I’m stuck at UVA for another semester.
Friend 2(on the phone): Bro it’s all good bro Berkeley’s grad school is lame anyway. Considering it’s so far to hangout I challenge you to a karaoke-off.
Friend 1(on the phone): Bro it is so on bro.
