BSB stands for “big screaming bitch” these women are always overweight, mean, and love to yell at other people’s kids or just random teenagers.They seem to think they are doing the right thing when really they just need to mind their own damn problems.

Liam: Hey bro watch out there’s a BSB watching us in her car.
