mo defs

short for "most definitely" (contrary to popular belief it is NOT mo def, and whoever said that is fucking retarded), used because saying most definitely sounds gay and mo defs sounds cool

Kid 1: dude that girl is so hot
Kid 2: most definitely
Kid 1: wtf
Kid 2: Uhh I mean mo defs

Kid 3: mo def
Kids 1 and 2: ...

mos def

The highest possible degree to which one can be Def. The is no higher level possible to which one can be def, therefore mos def is the epitamy of defness. There is only one known person to have achieved a true mos def status, that person, formerly known as Date Terrel Smith, then adopted the name of Mos Def upon pushing through the plateau. This level of deafness is the epitamy of hip hop culture.

At one point in my life, i believed that i could possibly be mos def, unfortunately after further review i realized that i was just a trick ass mark.

Mos-Def

As coined by the legendary rapper himself, "Mos-Def" refers to a thing, person, experience etc which is "mos" (or most, hugely, a lot), "def" (excellent, awesome; NOT short for 'definitely').

Mos-Def's changing his rap name to "Yasiin"?? Don't sweat it, he's still the MOS DEF rapper out.... after Chuck D of course..
