Doing something just to try it, even if you only do it once and never again; for the sake of adventure.

The police. So called because you look one time at them, as doing a double-take might attract attention.

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!"

Amongst other terms, the polite thing to yell when you see a cop cruising around, especially slowly.
