In paintball, when a player on one team and a player on the other team mark (shoot) each other at the same time, therfore resulting in a "one for one", one player is eliminated with another player from the opposing team.
Larry ran to bunker Steve and Steve shot Larry as Larry shot Steve. The ref couldn't tell who shot first, so he called a one for one.

san francisco bay area slang for a combination of cocaine and heroin, aka a "speedball". a hit of tar heroin and powder cocaine sold together on the street for $10 to $20.
if youre in a san francisco neighborhood such as the mission, and you hear a guy calling out "one on oners, one on oners", hes not challenging you to a game of basketball.
