Premise: ``Yo Momma'' drops the verbal gloves and ups the ante on trash-talking by making a competition of it. Host Wilmer Valderrama scours an inner-city neighborhood for the most original and skilled free-form trash-talkers, who take part in street-corner-style verbal battles based on the use of ``yo momma'' jokes. The sharpest ones to emerge eventually go head to head in a war of words before Valderrama crowns one snapper the best in the borough. The series ran for three seasons -- the first was filmed on the streets of Los Angeles, the second in New York, and the third in Atlanta. And many episodes featured guest appearance by rappers.
