When you kick a player from a game you host, normally the player is being kicked because they are a bad sport. If you are the bad sport, you won't find this documentation very interesting. There is two ways to kick a player, each with their own cause and effect. The first way to kick a player is to kick the player.

The next method after years of research
is the "You can leave now or I'll kick you when we have enough players" method. How does this work?

Step 1. "If you leave now I won't have to kick you when we get enough players"
Ironically they will know exactly who you are talking to.
Step 2. After they leave, simply say "Lol, It's just a prank bro"
Step 3. ??? Profit
