sisters before mister's 

what you say when a girl ditches her girlfriends to chill with her boyfriend
if a girl blows off her friends, or just hangs out with her boy instead of her girlies, and they're offended cuz they know they love her more.

similiar to guys's bro's before hoe's

Kate: oh sorry Ali i cant go get a mani-pedi with u and sylvia, im going to the movies with ben
Ali: aww, come on kate! sisters before mister's!!

Ali: hey kate come over to our table!! we got wings...
Kate;: hahaha no sorry, Ben already ordered wings too..
Ali: ugh, sisters before mister's!
