Meth Brain 

When a person has been awake for too many days on meth and they can no longer can form proper sentences, words get jumbled up and you get tongue tied. Your thought process is slim to none causing you to say things without thinking, focusing and concentrating are unrealistic goals, and your memory is completely shot. Usually a sign it's time to put the meth down and go the fuck to sleep.

"Damn dude Jessica's really got meth brain today doesn't she?"
"Yeah she's gotta lay off the meth for a while"

MathBrainOne 

He was the ultimate Minecraft player in legend. He had an extremely thorough understanding and knowledge of many glitches, exploits, strategies, mechanics, etc. Even ones kept secret that the best minecraft players don’t even know.

However, MathBrainOne was only a legend. We do not know when, or if, he first appeared and when he left. According to MathBrainToo, he appeared sometime around 2012 and disappeared around 2015. MathbrainToo is MathBrainOne’s successor and is the only one who can actually confirm MathBrainOne’s existence.

Well, that was until recently. What was just a legend passed down by a possible successor was in fact true. The mythical MathBrainOne made his eventual return in March of 2021. According to MathBrainOne, MathBrainToo was jealous of his extreme skill that he tried to take him out, and thought he pulled it off. But we now know that clearly failed.

They are due for a battle to the death to assert their dominance.

MathBrainToo 

MathBrainToo is one of the best minecraft players in planet Canada. He has a thorough understanding of Minecraft glitches, exploits, mechanics, and survival gameplay. That was true, until he wasn’t the greatest player anymore. A fallen hero only known by an old legend returned, the ultimate and mythical MathBrainOne. According to MathBrainOne, MathBrainToo was jealous of the skills of MathBrainOne, so he attempted to take him down, but failed.
