Math has officially claimed another victim! The moment you start seeing "lol" as |o| (absolute value of o), you've crossed the mathematical point of no return.
For the uninitiated, absolute value is just math's fancy way of saying "I don't care about your negative sign, just give me the positive distance from zero." So |o| would technically be... the absolute value of the letter o? Which is still just o?
The irony is that while they're losing their mind over mathematical notation, they're simultaneously using "lol" - which is exactly what the rest of us are doing at their mathematical breakdown. It's a recursive humor function!
