This could be either a really long or really short post, haha. I'll stick to the basics.
Bad drivers. (There are a million things you can do while driving to piss me off, so I'll lump them into one category.)
Liars. Do NOT lie to me—most likely I will find out and all trust you had of mine will be gone.
Cheaters. There is never a good reason. I have seen so many relationships ruined and people (including myself) destroyed by it. If you're unhappy or just incapable of being faithful, leave, or don't start a relationship. If you're a serial cheater then have the common decency to at least tell your s/o that you want an open relationship, and if they aren't into that, leave them so they can find someone better. Or, just develop some morals and quit fucking up people's lives.
Thieves. Your ass is grass if I catch you.
Slow walkers (and drivers.) I am naturally a super fast person, stemming from years of a paper route and marching band. Get. Out. Of. My. Way.
Super pervy people. You wanna tell me I have a great ass? Shit, I know. Boobies look delicious? That's cause they are. You wanna tongue-punch my fart-box and choke me while you jizz on my face? Get the fuck outta here with that. Want me to DM you nudes? Ain't happenin. Touch me inappropriately against my will? Your face meets my fist.
People who complain about their lives but will do nothing to change their situations or put any effort into fixing anything.
People who are shitty parents. If you're responsible for a child, the child needs to come first. So many people nowadays only think of themselves and what THEY want itstead of what's best for the child(ren) or just simply don't give a shit. Drives me up the wall.
Annnnd that's pretty much it. The major things at least.
