Nahhh I feel like it more the way they act than the way they look.
Like when I use it, it’s more in the sense of like “omg he so cute wtf”, “I just wanna squeeze him till he pops and eat him up”
(づ ̄ ³ ̄)づ ლ(´ڡ`ლ)
Even more so if he doesn’t look ‘stereotypically cute/ feminine” - it’s all abt the gap ε=ε=(ノ≧∇≦)ノ
And Killian was like a lil puppy following our mc around so cutely therefore he’s a bbg.
Though I’m not sure if that’s what everyone thinks, but that’s how I see it (▰˘◡˘▰)
Hmmm kinda difficult to explain cus I didn’t look up the actual definition when I first knew of the term and kinda based the definition from context clues but in my opinion, I just think it means when the man looks very appealing to women like maybe when they look very boyfriend material but it could also mean when the man looks feminine cus I have seen ppl call that type bby girl too

Omg why does killian look so bbygorl in this chapter
