Mario Lopez Debuts New 'Rated M' Underwear Line

By Michael Lopez

It looks like Mario Lopez has found yet another excuse to show off his famous abs. The Extra host is launching his own brand of "Rated M" underwear and recently stripped down to his skivvies to promote it.

Contrary to popular belief, the "M" does not stand for Mario. Lopez explained that he prefers to keep the letter ambiguous. He said it could stand for "Modern," "Masculine," or whatever his customers' prefer. The briefs do, however, have a nice little catchphrase sewn into the lining.

Every "Rated M" waistband reads, "For manful men and their very special guests."

And, proving that he's still a master of self-promotion, Mario is hyping his line all across the web. There are viral videos of him posing in the briefs, intricate websites, and even a "Rated M" Twitter handle for die-hard underwear fans.
