P.S. I forgot to add that "booger" is pronounced to rhyme with "sugar," but not with "cougar" (пума).

Also, I wanted to share this slightly disgusting joke from my childhood:

Q. What's the difference between boogers and caviar?
A. Some people have never eaten caviar.

A variant:

Q. What's the difference between boogers and fried liver?
A. No mother has ever said to her children, "STOP eating your liver!"
