Big Sean's track 'Dance (A$$)' is a filthy song.  That's why it's so hilarious that Sean's mom decided to read the lyrics for Jimmy Kimmel.

If you have listened to any of Big Sean's music, then you know his mom is a former English teacher in Detroit.  She introduced herself for the segment called, "Words From Your Mother" and proceeded to say ass with video of a one cheek twerk playing behind her.

The best part is when she breaks it down and quotes her son saying, "Make that M'r F'r Hammertime!"

If anyone thought that Sean's mom was a prudish school teacher, they definitely need to think again.
