What is One Time?
1.
The police. So called because you look one time at them, as doing a double-take might attract attention.
See Sir Mix-a-Lot's song "One Time's Got No Case".
2.
The cops. It's correct that it means looking more than once can draw attention. But the actual phrase comes from someone saying "one time" to let the other passengers or friends know that they have now seen the cops and are claiming the first look, and no one else should now turn around because two or more people looking increase your odds of being stopped by more than 50%.
"One time, man. Don't turn around!"

a great excuse for any possible situation, or a sure-fire way to get a chicky to hook up with you

2. "Hey, so ummmm... you and me? Just one time?"

What fans yell when Tiger Woods pwns bitches at golf. Started in 2005 at the Spanish Open, gained noterity in 2008 at the U.S. Open during Round 3-Hole 17 when a fan in the gallery yelled "One Time!" before Tiger Woods sank an improbable Third Stroke Par 4 to tie headed into the fourth round.
Commentator: "Well you can hit this just off the right foot, I've done it before with my bad knee...."
Anon. Fan: "ONE TIME!"
Both Commentators: "Woah!"
Commentator 1: "You gotta be kidding me..."
Commentator 2: "And he knows it too..."
(Tiger laughing in the background because he pwns all bishes...)

In jail, when the policeman walks around the pod checking in every cell, inmates yell "one time" to alert the other inmates that the police are doing their rounds. This allows people smoking, drinking, etc. to put away their contrabad before the man arrives.
'ONETIIIME' shouted the inmate to his brothes smoking
squares in his cell.
