An offensive, pungent, culinary based odor first identified by Eric Cartman in South Park episode 317 (aka "The Brown Noise") that has the power to affect the scent of anything and everything that may linger within its presence for an extended amount of time. Combine the smells of garlic breath, rotten fish, sour milk and socks worn for 3 days and you have Mecrab. Mecrab can occur globally, but tends to be more common among Asiatic cultures.
After an evening of drunken debauchery in celebration of the Chinese New Year, Mortimer plugged his nose while walking through China Town hoping to avoid the smell of Mecrab that no doubt will saturate the air from the hundreds of street vendors peddling strange delicacies and bizarre food items.
