If you think Big Sean's mother is a prude and afraid to keep it real, guess again. On the July 1st edition of 'Jimmy Kimmel Live!,' the Detroit rapper's mother recited a verse from her son's chart-topping song, 'Dance (Ass).' WTF?

We couldn't believe our eyes at first, but sure enough, Sean's mom was on the show for a special segment called "Words From Your Mother."

The matriarch, who is a former English teacher, graciously introduced herself, and then recited the chorus from Sean's booty anthem.

Looking poised and elegant, Sean's mother repeatedly said, "ass" with a visual of a bodacious woman twerking in the background. She even used profanity too! "Stop! Now make that motherf---er Hammer time," she said nonchalantly.

After reciting her lines, Big Sean's mom said, "That's my boy," and blew a kiss to her son.

We can only imagine what Big Sean is thinking right now. Who knows, she might join the G.O.O.D. Music crew and spit a few bars with Kanye West.

We kid, of course. The video is all in good fun.

Word to ya mutha.
