Double OT is double overtime. This occurs in sports such as hockey, soccer, basketball, etc. This is when the two teams are tied and after the first overtime session is over the score is still tied (whether at the same point value or more). Double overtime is where winners are crowned and dreams die.

This was referenced in White Iverson by Post Malone.
In overtime, it was 69 to 69 in the Yankees-Sox double header. Now at 71 to 71, they head into the next overtime. One might call it, Double OT.

Double OT like I'm KD, smoking OG.
