Being upfront with people. I do speak what i think and because of that i have gained a lot of people not like me. But that is okay deep down i am a happy person.

Not sure if i would say it’s my worst habit, but I do like to mess with White Christian people. I get a charge out of how clownish they act.

Interesting. When I issue forth a string of mental profanities it is always at my inferiors. Of course, they have no idea that they are...

I curse terribly when I’m driving. The county I live in is notorious for two or three cars running lights after they turn red...and other stupid shit. I have managed to avoid outright road rage by just screaming in the car. So far, anyway!

Being disingenuous is my chosen worst habit.
It helps get the best result from people, because being a condescending prick can be futile.
There's a spanish word that might be useful to you, "pendejo"

I suspect it may be arrogance. That or overeating

Thankfully you keep it in your head. I have gotten much better about that, but the occasional sarcasm slips out lol

Wow, if that is your worst habit, you must be an awful nice person.
I have few habits, daily swim, many cups of coffee.
Nastiest thing I do to people who annoy me is bend their brains. Insult them in ways they believe are compliments often to the point they repeat the comment thinking it means something good. It is easy in Oz. Our previous Prime Minister sought the suppository of all wisdom. Our then Treasurer, now our ambassador to the USA stated:
"I am not so conceited as to believe that I could have taken a seat in this chamber without the fulsome support of my beloved Liberal Party." (fulsome definition: expressing a lot of admiration or praise for someone, often too much, in a way that does not sound sincere: .)

Heroin....was. I'm better now. Wink, wink.

Mother superiors? ? lol...
