What kind of anime fans (or just fans in general) piss you off? (No offense)

I do not mean to offend in this thread but I just wanted to know what other people find annoying.

I know most would say weeaboos are annoying and yes I agree (BUT SOME ARE COOL PEOPLE OKAY BUT THEY ANNOY ME WHEN THEY SLIP SOME RANDOM JAPANESE WORDS INTO THE CONVO LIKE BRUH). The most annoying kind of fan that piss me to no end are the ones who: compare their favourite to other people's favourite and those who are arrogant af and acts as if they know everything about their favourites (Even though you were clearly the one who became a fan first). ヽ(`Д´)ﾉ
