חפשו מילה כלשהי, כמו slope:
 
1.
The sound a cat makes when it wants something or everything.
I knew it was dinnertime because I could hear the cat marping for food.

2.
When someone is performing oral sex (on a penis) and air is trapped within the mouth and is forced out to create a vulgar sound; much like a queef .
Dude this one girl gave me head last night and totally marped

HHAHAHAHAH SHE TOTALLY JUST GAVE OUT A BIG MARP

Oh man, I am so embarrassed that I kept marping on him ...
