Who doesn't know them?

You know that guy?
They buy a weapon for $4750, maybe you even dropped them a one for $4750 but all they do is headshot the guy with 50hp that just needed two rifle bullets, to wiff 3 times on the full HP guy not looking to then end up in the 1v1 against the guy with 5hp and while you tell them that the last one is low, the persist to go with the awp, miss their first shot, now have an empty mag, switch to the pistol in the middle of the gun fight and lose.
And maybe, just maybe this guy is you/me.
