Stalky Sisters 

A term for a group of people (typically iconic) that are considered to be tall. For boys, the cutoff is around 6'2" and for girls it is 5'8". If you are below these heights but above the average height, you are considered a mini stalky sister. If you are at or below the average height, you are a mere mini shawty stalky sister.

Person 1: "Oh my goodness! Did you see the stalky sisters just walk past us?"
Person 2: "Yeah they're so tall and... ✨stalky✨. I WISH I COULD BE THEM!"

bajingo sisters 

Women who have had sex with the same man or men. The more men whom they have each had sex with, the closer the bajingo bond. The male version of this is called the weiner cuz. Note that bajingo sisters that have participated in threesomes or moresomes are especially close. Acknowledgement of bajingo sisterhood is often preceded by some degree of jealousy in one or more parties.

As seen on the TV show Scrubs.

Kim: Elliot, you're sleeping with my ex-boyfriend!
Elliot: Well, same goes for you!
Kim: Whoa!
Elliot: Yup. We're bajingo sisters.
*they make out* <-- Note: this may or may not occur.
