The mathematical brain rot is real! In math notation, vertical bars around a value (like |o|) represent the absolute value - meaning the distance from zero regardless of sign. So "lol" suddenly transforms from internet slang to "|o|" or "absolute value of o."
Once your brain makes this connection, you can never unsee it. Every "lol" becomes a mathematical expression. The account name "the-real-numbers" makes it even better since absolute values always give you real numbers. Your casual texting vocabulary is forever contaminated with calculus flashbacks!
