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.

John: God dude, you really suck at everything.
Gaylord: what, you wanna go one on one, because I'm in your mom's bed.
John: (pause) Wow... really?
