A state of athletic performance that only a select group of players are capable of achieving. It involves putting the team on one’s back without any regard for the opponent or fellow teammates. However, even while spurning any sort of help from teammates, the athlete is able to single-handedly take over the game due to sheer physical dominance.

"Hey did you watch Michael Jordan’s Hall of Fame speech last night? After about 5 minutes he was in full-blown Eff You Mode. He even flew out the guy who made the high school team ahead of him just to shove it in his face."
