Majestic as fuck.

-Not written as an acronym-

Maf is a word for you to use in daily life as a classier way to emphasize how awesome something is. Use it to show how you feel about new songs that came out on soundcloud, someone's picture on instagram, or the latest Arizona Tea flavor.

Keep in mind this equation:
Majestic * Fuck = maf

Just remember to keep it maf.

p.s. Don't shy away from using the adjective hella to enhance the word maf.
"Brochacha, that quiche was hella maf."
