Why do u want to be an ass?

1. It is fun
2. Collecting comments on ur Steam profile full of rage is rewarding
3. The game is boring

If one or more of these points is true ur right here.

1. At the end of each round kick ur defeated opponent one more time
2. Use taunts during the match to signal to ur opponent that u have vicious intentions
3. Ki charge at least once when ur opponent lies defeated on the ground (for some reason the community decided that ki-charging is an insult, lol)
4. Another and very funny thing to do is t-bagging. Omg I love to do it, it basically tells your opponent you're laughing at him. Use it! U can do it after a round or whenever you think it fits.
4. Give ur character funny clothes. The funnier the clothes the more provocative ur opponent will perceive it.
5. Choose a provocative name. Insultive names wont do it. U need to put a message in ur name, examples are: "Are u mad?", "I'll make u hate the game, "U just got humiliated", "I step on u"
6. Winning. Yeah, sadly u have to win the matches. Nothing is more infuriating than losing. And if u keep losing, there is no way ur opponent is ever gonna get mad at u.
7. Lag switch. I haven't used it yet and it was only done to me so far, but I could imagine that this can be quite frustrating, especially when used during ur opponents juggle combos.
8. Profile picture. This is actually a small one, but it could add a little to the anger because a profile picture is what we first see when the loading screen pops up. It could be a mean smile or something that u think could be perceived as a provocation. Ur opponent will associate ur avatar with YOU! So whenever he thinks of u he thinks of that image which could be that mean smile and it will make him more angry.
9. A very effective but difficult thing to do is losing 2 rounds on purpose, and then winning the game. I never did this on purpose but when ever I won after losing 2 rounds it caused people to rage quit. U can use this as a tool to cause someone to rage quit but only try this if u know that ur skill level is far above the one's of ur opponent!

I hope u like the guide.
If u have any suggestions feel free to comment.

Good luck!
