What's with the word "Bud"

Has anyone else noticed that it is a common trend for salty and raging players to hid behind the word "Bud"? It's like they use it to try and throw off the tribunal for the toxic words. It's not a huge deal, but i keep seeing things like "You were bad, bud," "delete the game, bud," "I hope your parents die in a fire... bud."

Surely these players aren't ignorant enough to think that putting "bud" at the end of all of their toxic messages is going to save them... surely... surely not...
