camper

Someone who sits in a corner for 30 minutes; typically aiming down sight.

Severely lacking dopamine receptors since birth, campers will typically find this type of gameplay mentally tolerable.

Teammate 1: Dude, are you gonna sit in the corner and hold down ADS every round? You’re such a camper man. You legit don’t move till we’re all dead. Help take the objective man. Tired of watching your POV.
Scottiedoesnt: Dude, shut up. This is how I play the game. I can play it however I want.
Teammate 1: Bro, this is COD and it’s not even ranked.
