Charles Barkley Weight Watchers Ad Showcases Athlete's Knowledge of Penis Euphemisms (VIDEO)

Charles Barkley is bringing new meaning to Weight Watchers for Men's slogan, "Lose like a man."

In an ad for the weight loss company's male-friendly program, the former NBA star does his part to combat the obesity epidemic with one handy tip: losing weight makes your penis look bigger.

Reading off a list of euphemisms, including old favorites like "Johnson" and "Willie" combined with more creative phrases such as "Admiral Winkie" and "Buster McThunderstick," Barkley extends a long salute to all the men who are only helping themselves by getting fit.

Science seems to support Barkley's shtick. In an interview with WebMD, Dr. Ronald Tamler, co-director of the Men's Health Program at Mount Sinai in New York City, lends credence to Weight Watcher's hefty claim.

"One way I motivate my overweight patients is by telling them that they can appear to gain up to an inch in size simply by losing weight," he said.

Barkley has proven to be fearless in discussing his very public battle with weight, Parade notes. Back in April, he appeared in a Weight Watchers ad dressed fully in drag to promote message that dieting is not just for women.
