What’s up with eating ass? Is everyone doing it or is it all just an internet joke?

question: when I was 12 or 13 I watched a lot of filthy frank youtube videos because my big brother did as well, i went as far as commenting I Eat Ass and mor vulgar stuff that I can't remember on his YouTube and putting in my Instagram bio that "I eat ass" having no idea it was anything remotely sexual since I was a ignorant child that thought it was funny, little did I know my father's mistress was plotting against my family and taking screenshots of all these comments using it as her so called "proof" that I was raped and that I would be in orgies and eat ass. right now she has a child with him and he is fighting over custody for said child with a jury present and bringing this up as a way to discredit him my question is how do I explain why I said "i eat ass" online to complete strangers who might be unaware of the joke or simply too naïve to try to understand and take it at face value.
