What is the most annoying habit someone can have?

Probably chewing loudly.... snoring like a hog with asthma.... being crude etc etc lol!

Lying all the time.

Gossip, non stop.

prying into the personal business of others, to it on a continuous basis, there were a number of people like that at the job where I retired.

I’m sorry to say this but smoking

Smoking or snapping gum.

Smoking💀

straightening themselves out in public.. eh!

like, dude, if it's that bad go home and jack the hell off in private already!

crosseyed, not a habit but damn I hate it, should I look at the left or the right, and when I think I look at the right then the other move 😯

Making too much noise eating, being fidgety, taking during movies, not covering mouth when coughing..

When they say “do you know what I mean?” at the end of every sentence. Or “do you get me?”

Disgusting eating habits like ramming food down fast and eating noisily.
Untidiness.

Ignoring people

Picking there friggin nose. Omg. Lol

For women it's called breathing

mouth breathing

Smoking, or chewing with mouth open.
