Mfof stands for "Mouth full of
food" and is used to describe when someone speaks in an incoherent, or unclear way. Useful against the following: Drawls, drunkspeak, Foreign accents, lisps and people who speak before swallowing their
food or other edible/inedible substances.
Funnily enough, pronouncing Mfof sounds as if you're trying to say something through a mouth full of
food.
"I swear, Ben came home drunk again and spoke Mfof up till he fell on the floor! Couldn't understand a word of that man."
"That French,
German and Scandinavian exchange student can barely speak English! Sounds like a bunch of Mfof to me."
"Jimmy got stung by a
bee on his lip! All I hear is Mfof when he speaks now,
haha!"
