This is when you go to California to visit your friends who you have known forever so you call each other "family", hence the cousin thing, when they actually are not related to you in any way so it’s NOT incest *don’t freak out* …so one thing leads to another and before you know it your gettin fuckin rammed deep by your "cousin" while sucking his homies dick. You’re welcome

Cousin is a euphemism for menstruation. Instead of saying "period", girls often say "My cousin is here", or "My cousin has come", or sometimes "My cousin is visiting", to express the idea "I'm on my period".
Amanda: Girls, I can't hang out with you tonight. My cousin is here.
Sadie: Oh, sorry to hear that. You're having period cramps agaian?
Amanda: Yep. They'are killing me righg now.
