Derives from the ever popular movie american pie. as in: "this one time at band camp." But now has more wide range of usage. Guys who are usually stoners or alcoholics use this term to reflect on one or more experiences they've had while under the influence. And wish to use this term to enlighten us all about the joys and wonders of "trppin"
Stoner Dude: This one time me and Bob were totally trippin out in the back alley way behind Fry's. Then all of a sudden we here these sirens, so we run. And then we just keep runnin and runnin till we reach this babes house and theres like 8 naked chicks in this hot tub. and we just went back there and then i checked my roley. it was already 7 o'clock. past my curfew. my probation officer would kill me. so i had to bounce on home. but man it was trippy.

Doing something just to try it, even if you only do it once and never again; for the sake of adventure.
"Dude let's try it, one time for the one time." #YOLO

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.
