My turn!
I was playing in a random hard game with my lvl5 Firebug perk.
Then this lvl1 commando joins, and his weapon of choice is the LAR.
I try telling him the game he's in is hard, and he should switch to a begginer/normal server and level up his perks. Or, if he wanted so badly to play there, at least pick weapons corresponding to his perk.
As any noob would say, he asked me kindly to **** myself.
Wave ends, I switch to medic in an attempt to keep the other players (and the noob) alive. But I was a firebug on the previous wave, and I was top of the scoreboard. The noob asked me for money, I gave it. He bought... a flamethrower.
I told him again that if he wanted to use a weapon, at least pick the same perk as the weapon. He asked me to **** myself again, and kept using commando.
New wave starts, he kills himself with his flamethrower. And blames ME for not healing him.
Another player points out he died, and I say "no amount of healing could've saved him".
Noob rage quits.
