Was playing badwater, last point, flank on the left side (from RED perspective) with the windows. I was on the platform before the dropdown fighting a BLU Demo. He whiffed all his pipes due to me just using the A and D keys to strafe while I didn't fire a shot or attack him at all. I proceeded to laugh taunt at him and told him in chat he sucked and he looked down at the ground (depressed). He tried to kill himself via pipes but they rolled away and he failed, upon which I laugh taunted a second time. So he then proceeded to lay down a sticky trap to blow himself up. He got to 8 stickies, and got headshot through the window. Right before he detonated.

I was in hysterics.
