Canadian slang for "Bye", "Take care", etc. more specifically used in the city of Ottawa. It can be used in various contexts, whether you're leaving a place, ending a conversation, or saying farewell to someone who is departing.

Could be shortened to just, "One".
Also written on text sometimes as, "1t".
1: "I'ma head out, bro, one time, fam"

Get the One time mug.
South Central Los Angeles in the late 80s when the police would pull onto the street in the projects, the young gangster lookouts would holler out "one time" or "two times" or more etc. depending on how many patrol cars were coming down the street. One time meant a single unit on routine patrol. Two times or more meant a bust was coming.

Cops. Police. Benny Blanco. Pigs. Fuzz. Twelve. Task. Rollers. Knockos/Narcos. Jake. Grass.

I was always told it came from the fact that it only takes one time for the cops to pull you over and f*** your life up with a case; however, popular opinion claims that it comes from the fact that glancing at cops one time can get you blurred.

a LIE. When your drum major/band director decides to not be satisfied with the band's "final" run through.
Drum Major/Band Director: "All right band, One More Time!"
Band: "Oh god, not this again."

Used to express "me time," but played off of the phrase "one on one time."
