Big Brother

A person who clips literally everything and most of the time does it without you even knowing. They could be recording for absolutely no reason, or hoping you'd say something weird, embarrassing, or damning so they can use it against you, expose you, or even use it as blackmail material. It also doesn't have to be recordings, they can also screenshot everything you send to them or in a group chat.

Person #1: Got him! Fucked the shit out of that guy!
Person #2: Clipped that.
Person #1: Can you stop acting like you're Big Brother? ffs

Decoy deploy

A type of revenge kill in a multiplayer video game where one is killed by another, but said person who was killed respawns right next to their killer, who then proceeds to kill them.

The name comes from a tool on Roblox, which has the same name, which allows the player with the tool equipped to spawn a duplicate of their avatar to trick enemies into killing the duplicate instead of you.

Person A kills Person B in an online game, then Person A says:
"ez"

Person B, luckily, spawns next to Person A completely at random and kills him, Person B then says:
"Decoy deploy."
