An affectionate word for a sister, or someone regarded as a sister. It can be a nickname given to someone who acts sisterly, kind, sweet, and caring.

It's also used as an affectionate word by many in the transgender community for transgender women who love being super girly, cute, and sweet a lot more than average. It can be a kink, or an interest to them.

Since it started as a word for sister it was later used as a derogatory word by sexist people that believe if you were born a guy you shouldn't be effeminate.

A degrading word for a man who is feminine, might wear women’s clothes, prefers to be themselves over a stereotypical man. Probably has issues with self Image and insecurities.
Might come off weak but will most likely tell you wear to go if they must.
Bully: you see that sissy? I’m gonna call him a fagot and push him around.

Sissy: starts to cry then proceeds to knock the bully’s teeth down there through.

Female whiteness: gurl that was amazing! Don’t listen to them, your beautiful inside and out!

Originally defined as "wimp", "pussy" or "weak" the word sissy has morphed into the perfect def'n of a Brazilian footballer.
Brazilian guy: "Hey man, that Brazzer baller is down crying for mom. He's hurt bad!"
Normal guy: "Nah dude, he's just a sissy. Get out the spray. His vagina is sore. Stop complaining and be a man (bitch slaps Brazzer)"
