sibling switcher

when someone dates one sibling, they break up, then the person dates their brother, then on and on with the family like how a homie hopper jumps homies, but it's siblings

"Dude he's such a sibling switcher, he dated me now he's with my brother"

Sibling

Someone who invaded your life through your mother's uterus (Or an orphanage)
They drive you mad and you drive them mad, but no one else can drive you or them mad.
They ruin your life but they kinda don't
Siblings are confusing little shits
And they are also little fucking snitches

Sibling: "HEY I NEED--"
me: "SHUT DA FUC UP"
Sibling: "But someone is bullying me!"
Me: *I'll kill them*
