Eikmouch
When the big, overweight and hefty guy that everyone knows for infamously getting away with eating/drinking your food(s) or beverages. He looks scary that you might "Eik" in fear, and he's that "Mouch" we all know, he's "The Eikmouch".
Yo! So "The Eikmouch", asked to "try one bite of my sandwich" during lunch, he ended up eating half of it in one bite! What a scab.
