Doing a Jackerco 

''Doing a Jackerco'' is a popular term used in the Overwatch community, the term is usually used when someone does some insane dodging, but the actual definition is a bit different. The term was made popular by the Overwatch player Jackerco who invented the tactic. To do a Jackerco means to spin your mouse so fast that you do at least five 360s every second while you're also crouch and A +D spamming at the same time. This confuses your enemy and stops you from getting headshot. It's basically just a more advanced version of normal dodging tactics.

Person A: Wow those are some INSANE Jackercos dude!
Person B: Thanks, I've been practicing them
Person A: Yeah, you are really good at Doing a Jackerco!
