So the most important thing about annoying people in tf2 is to always taunt after a kill. You must remember this, even if you know you will die, taunt after a kill. Another really important thing is to wear gibus and pyrovision goggles, now this may not sound like much but it really gets on people's nerves. So another thing, you really want to play sniper and never EVER leave spawn. Just sit in spawn and never poke your head out, you might want to a little bit just to get a clearer shot but that is an exception. If you are a 9 year old it would help in this part because I now tell you to mic spam REALLY hard. The reason it helps if you are a 9 year old is that it would be way more effective than if a 40 year old with a really deep voice tried it. Something else that helps is if you go completely out of your way to single out one person or try your absolute hardest to only get taunt kills.

There are actually two sections. Here is something that may show you some pointers on how to annoy people. (contains some profanity)
