all the classic ones,
Kicking butt in BF2 with the apache, sniping an admin out of an apache with the M95(HAXORS).
Joining games of DoTA when trying a new character and being kicked for choosing the character that host wanted, choosing SA, BH or clinkz [invis/assassin characters].
Being awesome in CS surf(source), and knifing an admin who sounded like he was 12 while surfing (permaban :'( meh), when playing a mod-ed server on CS:source where one class could go 100% invis, i just got the Magnum and when i heard footsteps BAM!! worked 19/20 times, was obviously aim-botting as i killed him at almost melee range with a 1 shot gun.
LFD after team left me to die on purpose when i was downed (downed by them), next stage i greifed a bit, then when i went down i took them with me (teamed up with the infected).
And TF2 for killing someone with the pyro-heavy-sniper taunts all in one round, red team spam hacks and votekick (server went down anyway).
Now because of said people i only play TF2, BF BC2, Leauge of Legends (like dota), and on very rare occasions (once every three months or so) DoTA, just to remind me why i stopped playing that.
