romsae for saerom cause duh, it's too iconic to leave out. sometimes I like making it romddae to amp up the aegyo lmao
for s.coups I've personally found coupsie rather cute haha. i also find the random 4 syllable words kfans call him (asparagus, anyone?) hilarious. cheol, cheollie, cherry are also all very cute
apart from the utterly iconic exy sexy megan foxy, i don't think I know much for exy?? like sometimes I'll call her by her real name sojung and that's IT no nicknames really
same for (shinee) minho like i don't think i use anything beyond the government assigned flaming charisma minho (and that too only when referring to the dibidibidis rap tbh). he's mostly just minho to me
for dahyun it's either dubu or newjeans' 6th member (the latter is a joke on reddit lmao). this thread is making me realise I'm really not all that big on nicknames
but yeah that aside, well idk if I'm calling him a bias rn or not seeing as he isn't a debuted idol yet, but boys planet's haruto is my favourite contestant, and i really like the nickname ruto. idk it's cute
