Big Sum Bitch When someone is so big and can't get out of their own way but you don't have time to talk to them so you just call them BSB

Craig is such a BSB. He wouldn't move last night.

A shorter way of saying British Soft Boy These types of guys usually have brown hair, tall, usually white, obviously from the uk and just in general the most sweetest person ever. Mostly actors who are aged 20-25 are the typical British soft boy. (I would say this in texts instead of irl..)

A: Did you see Alex Lawther in The End Of The F****king World?! He was amazing!! B: Omg yess!! He’s a BSB A: A what?? B: A British Soft Boy <3

Big.Sexy.Brain. All of the intangible reasons you find a person sexy. Their laugh, their smarts or their sense of humor. BSB can even be attributed to being attracted to unconventionally attractive people/elements of a person.Their freckles, or red hair, or their chubbiness. BSB is an unconventional thing that attracts you to someone else.

'That guy over there has BSB.' "The one with the freckles? Oh yes" "I'm attracted to them because of their BSB."
