Infinite Retard Loop

A phenomenon in which an online interaction devolves into stupid, outlandish, and otherwise nonsensical rhetoric as each participant attempts to outdo the other person with increasingly inane or absurd fallacies/observations. Leading to a scenario in which the conversation becomes more and more insane or nonsensical as it progresses.

I was in a comment section where this debate about geopolitics went from cordial to the one person accusing the other of trying to marry his dad. How did that even happen?
Dude, that's the Infinite Retard Loop.
