Sister in-law

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.

5 years ago:
Bianka: Hi my name is Bianka I love your brother.
Sister in law: You are not good enough for my brother he deserves to be with someone like Britney Spears.

Today
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.

sister-kisser 

In a game a very close tie. A hard fought game that ends in a tie.

The Redskins and the Rams had an up-down game and it ended 27-27 in a real sister-kisser!

Sister Tom 

The homosexual equivalent to an Uncle Tom. A homosexual who simply plays up to the stereotypes of how a homosexual is expected to act in order to gain approval.

After Robbie came out of the closet he keeps playing up how much he knows about fashion, but I really don't think he's even all that interested in fashion. He's such a Sister Tom.

sister's pants 

(noun) 1. skinny jeans when wore by men. 2. pants so overly tappered and tight, they look like they were borrowed from your sister.

1. John completed his Emo look by wearing a pair of sister's pants. 2. "Man, look at that kid over there," exclaimed Derick as he pointed out a 20-something year old man wearing a pair of sausage-tight jeans, "how can those sister's pants be comfortable!"
