Sister Twins 

Friends who are sisters, but more. They are alike in almost every way! They don't have to necessarily look alike.

Chloe and Erin are sister twins!

It is when you tuck your penis in between your legs to make it look like you have a vagina.

When he showed me his twin sister I gagged in my mouth!

eyebrows are sisters, not twins 

It means that your eyebrows are not meant to be identical.

- God, my eyebrows are not symmetrical
- Girl, eyebrows are sisters, not twins!

Twin Sisters 

A less crass way of saying a pair of tits

This beat is colder than two diamonds on twin sisters

Twin Burrito Sisters

Pair of two girls that are the bestest friends in the world and are super nice. Usually one of them will be a bitch, but once you get to know her, she will be an amazing person and friend. Also will fall for any guy. The other one will be super shy and introverted at first. But, then as you get to know her, she becomes the life of the party and is amazing to have around. As a bonus, they are both thicc asfff. Great to have around as they are both very weird and funny.

Dang look at them. I bet they're Twin Burrito Sisters.
