What is Mathole?
1.
(Math-hole, emulating
Matholes like to talk about all the fancy things they're currently doing in their glorious advanced math class, but usually cannot help you with your regular math homework. Do not even ask.
Matholes are annoying despite the fact that you probably have a few of them for friends, which doubles the annoyance. You're not bitter that you aren't taking their advanced math class, too; you're just rightfully pissed that they proclaim to be the math god{dess} but cannot help you with your "simple, easy" homework.
Mathole: "And tomorrow we're talking about {insert fancy pants math subject here}! Oh man, I love math. I'm so good at it. No one is better than me!"
Mathole's friend: "Oh, maybe you could help me with {regular math subject}?"
Mathole: "Oh... uh, I was sick that day. I don't remember it.*moves on to tell a fellow mathole an inside math joke that no one appreciates except those hopelessly enslaved to matholedom*"
Mathole's justifiably irritated friend: "*thinks* I wish my friend wasn't such a mathole."
