TKO is a boxing term that means “Technical Knockout”. A TKO occurs when one fighter knocks the other down 3 times in a single round, and is automatically declared the winner.
TKO is also a slang term which can mean that someone has been rejected (romantically) by another 3 times. This slang term has become more popular with the recent release of Justin Timberlake’s song “TKO”. In this song you can hear the lyrics “I’m down for the count ya girl you knocked me out…TKO“.
