Giving a blow job for 20 minutes and not even a thank you! Men!

Spit. Chew with their mouth open. Cough or sneeze without covering mouth. Talk with food on their face. Ball scratching. Toe picking. Don't wash their hands. There are so many really.

The dickless f -face.

Spitting is nasty. Beyond that just lack of body maintenance.

People blowing their noses onto the ground or whatever is near with just their fingers out in the open. Grosses me the fuck out!

Here's another one- college dormitory lobby sofas!! Nasty. There's no telling what's been done on them and by whom. Sitter, beware!

Eating while taking a dump. I've never actually witnessed this but you know someone somewhere is doing it. Maybe it's a bowl of chili or curry. Think about it...

Blow their nose at the dinner table.

Sorry. I lost a dirt-eating contest as a kid. I'm going to have to recuse myself on passing judgment on what's gross.

Smacking or slurping while eating. Like nails on a chalk board. Smoking. And then throwing butts on the ground. Shameful. Phlegmy coughs.

This is just what grosses me out. I have a huge list of pet peeves.

eating with lots of noise & open mouth.

I'll probably catch hell for this.
Obese people in tight or revealing clothing (shirts 3 sizes to small, short shorts, lowriders [I don't want to see what type underwear you have on or don't], plumbers cracks, V necks to their belly button). I mean c'mon your not a teenager anymore. I don't mean wear baggy clothing to hide in or not wear comfortable clothing, just don't show so much canvas.

Chewing with mouth open, farting in public

3 second rule. Someone I had just begun dating introduced me to this. A nacho or something we happened to be snacking on in my apartment fell to the floor. She then grinned and yelled "3 second rule!" As I had never heard of it before I said "what's that?" She explained it to me and as I was like waiting for the punchline, she proceeded to eat the food that hit the floor. I was soooooo turned off\grossed out.

Reading all these comments!! Ugh.

A damp/sweaty handshake. PUKE!

#1 Sneezing!

Spitting in public grosses me out.

people kissing their dog (or cat) on the muzzle, or getting licked in the face by either.
didn't buddy just sniff the neighbour bitch's arse? tiger lick her own?
beurrrrk....

Yes, hands on the buffet food
Not washing hands after using the restroom (I won't be inviting them to my potluck)

Double dipping chips into dip being shared with someone else.

I agree with many of the earlier comments especially not washing hands after using the restroom or before cooking, or even before putting dishes away that have been washed.

First things that come to mind - someone spitting a big wad of phelgm on the sidewalk.
And a time I was in Walmart - a very hefty, economy size young woman was walking ahead of me, wearing thin - T-shirt material shorts. Up in the crack of her butt , there was an obvious brown stain ...
That did it !

Knuckle cracking.

Cracking knuckles, bbbbrrrrrbllaa##!!!?

It sounds like breaking bones
