Named after the Overwatch League Team, Houston Outlaws, the word Houstonable means going 0-2 against a team, then losing the game 3-2, since Houston outlaws do this so repeatedly against other teams, the word Houstonable has been adapted to the watchers of the OWL.
Person 1: Hey, did you know that the Miami Mayhem is going 2-0 against the San Fransico Shock?
Houston Chad: Houstonable.
