When something (often a joke) is taken to the extreme.

Friend 1: "Yeah, I bouta hit up the club!"
Friend 2: "Make sure you have a cute outfit."
Friend 1: "Oh, I will, with my matching shirt and shoes."
Friend 2: "That should be cute."
Friend 1: "And my matching socks and weave."
Friend 2: "Ok, run out." OR "You can out."

in Swedish the word slut means run out in English which causes some very confusing yet often hilarious insult moments for your lulz.

Commonly seen in Rainbow Six Seige, "running out" is when a Defending op runs out of the building at the start of the round to get a cheap kill. This way of playing is very toxic and looked down in the community. basically any op can run out but mostly seen by: Jäger, Bandit, Vigil or just anyone with an Acog. Plz stahp running out...
Ash: Wow, fucking Vigil ran out on me. Reported for running out
Thermite: What? How did he one-tap me like that, ranked is fucking rigged and bullshit.
Vigil: lol ez get gud fgt.
