I've been told I have an "angry face", or people have assumed I was angry when I wasn't, on a regular basis. My daughter and her friend were playing in the back yard and I overheard her friend ask why I was so angry all the time. My daughter: "He's not angry, it's just his face."
When I was electrical technical supervisor, by mechanical equivalent was called "Angry Doug". We'd known each other for twenty years. He was just blunt, and not particularly angry. People had difficulty sussing the difference, I guess.
I also had the nickname "Mumbles" that went on for years. My daughter: "Rubble, rubble, ruble, heh, heh, heh. Right Dad?".
I've been written up for getting into shouting matches with superiors. I tend to be very protective of the people who reported to me. I never bought the whole "Women are emotional, men are rational." Everyone is emotional, but the degree or type of emotions that are traditionally seen as socially acceptable are different.
