DBO

-noun Dead Ball Out. In slow pitch softball when the maximum allowance of team homeruns has been met, any further homeruns will count as an out. Any homeruns exceeding the limit will be declared a dead ball out, or DBO, by the umpire. Frequently, DBO offenders can be quoted as saying "Screw the team, I'm going deep."

Swing lost the state championship for his team because he hit a game ending DBO with the tying run on third base.

DBO

An abbreviation for Diarrhea BlowOut. A DBO is a special type of shit. It isn't any normal case of the runs, but rather the type that makes your sphincter ache for days. Some traits of a DBO are loud anal vibrations, hot burning sensations, and a powerful jet stream often accompanied by splashing.
