Sister Punch

An alcoholic punch spiked with Xanax by sorority girls, in secret and at random.
Generally for sorority-only events and parties.
Often a means for fellow sisters to seduce one-another.
Lesbian orgies have resulted.

O.M.G who made the sister punch last night?!
I don’t remember anything after Emily brought me to her room LOL!

Sister Aunt

When your mother starts having babies before your granny stops having babies, and now you are 3 years older than your aunt, but you're both raised like siblings.

Mama if you get pregnant now, my child will be a sister Aunt.
