Snot, phlegm, boogers, that thick substance you can't get rid of no matter how many times you blow your nose when you've got a respiratory infection. Akin to lung cheese, except in your nose.

When you unexpectedly walk into a bathroom that someone has just destroyed with a massive dookie bomb. The initial shock of the pungent odor filling your nose makes you stand stiff as your eyes roll back in your head. If you've ever experienced these symptoms, you were the victim of a Nostril Knockout....and it sucks to be you.

*Note* Old, overweight truckers who eat cloves of garlic whole, are the undisputed kings of the porcelain. It'd take years of training (and junk food) to dethrone them.

Ejaculating into ones nostril filling it to compasity!

A person with huge nostrils that often flair, or pulsate when excited or talking.

The worms eye view of big nostrils, especially in a music video.

When a person's nostril holes are higher than their septum.

This is a comical way of saying that someone has weird, solitary habits or obsessions.

When your nostrils are so soft, they feel like a baby horses nostrils.
