You don't have to be so snotty.

I know that Tom was a snotty child.

Mennad's helmet is full of snot.

Because he was wearing a mask, nobody could see the snot hanging pendulously from Tom's left nostril.

You have a little bit of snot dripping out of your nose.

Snot is pouring out of my nose.

Turkey's Sea of Marmara is battling an explosion of sea algae, dubbed sea snot, which is now threatening an ecological disaster.

You little snot!

I laugh at people, while there's snot at my nose.

Tom is a snotty child.
