Sinista 

When someone you know who's close to you is planning bad intentions for you or your crew while acting like everything's still Legit.

She invited him to her party, even though she knew her ex-boyfriend and his creeps were gonna show up. That's some sinista shit she played out.

Sinisha 

Derived from the Serbo-Croatian word for son, Sinisha is the name of a cool guy. He may be a bit angry at times and maybe a bit rude but you can trust Sinisha to pull through even if things aren't going too great.

Person 1: "Damn, why is that guy so mad?"
Person 2: "Just give him time. He's a Sinisha."
