When performing cunnalingus on a woman whose pubes have heretofore never been trimmed. The experience can best be compared to slogging through the Mekong River Delta c. 1968. The fear grips you. You're back in the 'shit!
Hesh: I met this chick last night. She was hot, beautiful and amazing. I took her back to my crib and we got busy. All was great until I hit the sticky place. Man, she was a beast! I was Munching the Mekong; she was so hairy.
The act of performing oral sex on someone while you are afflicted with a cold or upper respiratory ailment, causing a snorting sound similar to that made by a moose, horse, deer, etc.
So she decided to go down on me last night even though she had a sinus infection. I told her it was a bad idea but next thing I know there she is Moose Munching me.
