dumbinant 

A BDSM lifestyle term for an idiot that considers him or herself to be a Dominant of submissives and slaves in the lifestyle.

Wow! That guy is a dumbinant if he thinks he can tell my Dominant's submissives what to do without seeking his permission.

Any idiot that thinks he can make me submit just because he thinks he is a Dominant is really a dumbinant and a jerk

Dumbening

Young Abraham quickly went from smart as a monkey to dumb as a chimp, as a result of his dumbening.

Dumbee

A dumbee is a person who appears to be dumb. The beauty of the word 'dumbee' is that it is not actually an insult therefore the person you say it to cannot tell tales and shiz. This is how Prince Ali created this word.

Dumbee is the word you can switch to if you're about to call someone a dumbass.

DUMBEE! Saving friendships everyday.

(PS - Saying dumbee automatically makes you a lot cooler.)

Crybaby: *does something wrong*
Prince Ali: Stop it you dumba-...dumbee!
Crybaby: I'm telling off you!
Prince Ali: It's not like I actually insulted you, dude.
