sitship 

sitship-A situational relationship that should be sexual but is not because female is too self conscious about her body. So we never fuck and relationship, situationship just sits.

The bitch is smokin with a phat ass, but she thinks shes fat, hence our sitship

sistership 

Being an older or younger sister you give your siblings (younger or older) your sistership. Which is being dedicated to your siblings relationship.

brother: hey, where’s my birthday present?
sister: i give you my sistership ya ungrateful bitch.
