Gearing

To be overwhelmingly skillful at an activity, or to overcome extreme hardship. Typically used in the context of a 2D fighting game. A term originally used in the underground fighting game scene in the early 2010s, arose from EVO 2012's Street Fighter IV. It is unknown why it is called "Gearing", but some speculate it could either represent how functional one is, or represent the Guilty Gear franchise, as it rose in popularity in the early 2020s.

A: "WAIT, HOW'D YOU WIN EVO, YOU WERE TRASH!"
