Guy 1: Who's that girl over there?
Guy 2: Oh, that's Ma'ayan. Last night she had her big stage performance accompanying adele after two hours of swim practice, and still was able to get all of her homework done.
Guy 1: wow.
Guy2: But that's not all. She also manages to maintain her 4.5 average in school and is a size 00.
Guy 1: WOW. Is she available?
Guy 2: -_-
The Hebrew word for an old, wrinkly, smelly, and quite rude old man with horrid fashion sense and a large nose. He is usually the leader of Rosh Hashanah services, and frequently farts accidentally into the microphone. Unfortunately, he has horrible hearing and doesn't realize what he's done.
"Oh no, we have to go to services this year and listen to that Ma'ayan again..."
"Ew, I hate that Ma'ayan. He's so ugly and smells like a pig."
