Is OTHER wrong in the post ? POST : For background’s sake, I’ve been dating my boyfriend for around 4 months now and ever since then he’s been calling me Fatty as a nickname (I’m 5’6” and 150 pounds). I hate this nickname so I asked him to call me by another nickname or to call me by my first name. 

He opted to call me “Hihi”, which coincidentally is the slang for “asshole” for young people from my city (shoutout to Hong Kong peeps). He’s 14 years older than me (he’s 38 and I’m 24) so I can’t say for sure that he knows this term. I told him that it’s a rude word and don’t call me that. He persisted. AITA for getting mad even though he might not know what it means?
