What makes you suuuuper mad?

I HATE when people use the word "merk." The color brown. Oh, and I hate when girls like flirt or date EVERYONE. Like, my one friend has either talked, or flirted with all these people. And thier all friends. She's such a skank. Like, she goes around saying shes ugly and fat, but next she's wearing short shorts and tank tops and flirting with every guy on the planet. She dos'nt even like any of the guys that she talks to, like she will send them nudes and be all flirty just to get called pretty, but then she'll say she hates them next. Hahah,k whatever. But, What pisses you off? Please feel free to explain.
