Sibling Couples

Two people who happen to be dating and also happen to look like they are siblings; generally greeted with fear and disgust. Normally they are made fun of by people who have no idea who they are but see them 'macking' on each other in public.

Extra Points: They dress similarly. They have similar names. They randomly have the same last name and/or they are actually siblings.

"In the long run it's a good thing you and Fredrick didn't go out, because you would be one of those gross sibling couples."

Sibling couples awk me out!

Half Sibling

Siblings whom have only one common parent whether it's their mother or their father. Half-siblings sometimes are raised together, but more commonly raised in their two separate families. Half-siblings are typically separated and have somewhat distant relationships, when not raised together which is very common. If you have half-siblings, you call them brother, sister, not "half", or you call them nothing....

Half Sibling -

I love you, brothers and sisters. We should catch up sometime.. :)

sibling slut

A person who switches their best friend from one sibling to another sibling more than once.

Jessica used to be best friends with my sister, Taylor. After a few years she was tired of that and became my best friend. That sibling slut traded me in for Taylor the other day.

Sibling Love

The feeling of obligation, loyalty, and affection, shared between persons who traditionally but not always share one or more parents, despite the terrible things they did to one another as children and sometimes to one another as adults.

Clara and Tony feel sibling love for Libby, even though, during childhood, Tony and Clara would use a television remote to convince Libby that she was invisible and mute.
