Person #1: "Shhh! Hold on, I'm mathing!!"
Person #2: *confused*
Person #2: "Don't you mean you're doing
math!?"
Person #1: "NO!! I'm mathing, so shut up so I can figure this out!!"
Person #2: "Wow, okay then..."
Person #1: "Thanks, now I need to
math all over again because you interrupted me!
Ugh!!"
Person #2: "But it's simple
math, you'll live!"
Person #1: "But mathing is hard!!"
Basically it's used when the person preforming the act of mathematics has an already difficult time doing simple
math, making them frustrated and forcing them to explain why "mathing is hard, yo!"
