up on one 

On one wheel, as in a wheelie or a stoppie, on a motorcycle.

I saw a great stunt show, the stunna was up on one and grabbed a Red Bull out of some chick's hand.

Man, I am still working on a simple wheelie.

one on 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.
