on you"

sisoy

"Sisoy" is a new popular expression used by teens around Spain that popularized TikTok.
It is a contraction of two words: si (yes) and ser (be).
The meaning might be subjective and vary from places, but it mainly means <<Me too>>,
expressing that you correlate and feel identified with the things that someone mentioned.
Note: this word is highly hated by many people so use it wisely.

Example 1 (Spanish):
-He suspendido tres asignaturas, ya no de que hacer para aprobar
-Sisoy😹

Example 2 (English):
-I have failed too many tests, I think I'm gonna just get a sugar daddy

-Sisoy

Dong sister

2 female friends who have touched the same dong. No p in v or blowies required. The female version of Eskimo brothers.

Chloe stuck Sean's dong in her mouth and Beth gave it a handy. Now Chloe and Beth are dong sisters.

sister and brother

It is two persons of the opposite sex who are always there for each other. They can not even be related but trust each other anyways as if they were 'brother and sister' These 2 persons can never lose faith in each other because they will need each other. In one way or another they will always love each other no matter what, and no one can separate them.

I love have a sister and brother relationship.
