Is a sister much like an evil step sister
that you get pasella when you marry the idiot that you thought was the love of your life but is actually a lazy motherfucker who still needs his ass wiped by his mommy. Anyhow Sister-in-law is nother like a sister most of them are fat ugly bitches that should just die horrible painfull deaths. To narrow it down they are ugly bloodsucking wankers.

Sister in law: You are not good enough for my brother he deserves to be with someone like Britney Spears.
Sister in-law: OMG my brother deserves better.
Bianka: o go fuck yourself ugly bitch I think he deserves Britney spears they are both useless fuckers that are soooo stupid and they both have smelly arm pitts.
