(fair warning some if not all of these are bad, don't take it too seriously.)
Aespa: Ey. this is by far the stupidest one, because it sounds like æ and also it's Middle English for egg and I think that's funny
Big Bang: Stardust. I know their concept has nothing to do with space but hear me out. everything is made out of the same stuff that was made in the beginning, often expressed as stardust. I think that's a sweet meaning
EXO: Alien. because it fits their concept and I like it better
F(x): Y. it sounds kinda bad but in math f(x)=y so suck it
9 muses: Devotee. their name is based on greek mythology and someone who was especially dedicated to one of the gods was called a devotee.
Spica: Vir. because spica is in the Virgo constellation and Vir is the shortened designation for stars in that constellation
History: lore. cool sounding synonym.
Argon: there's 2 possibilities for this: Argonauts because it has the word argon in it and has a cool history, or Neon because argon the element glows
B.A.P: Bop. a huge flex and calling fans baby makes me uncomfortable.
