According to Urban Dictionary, a cankle is "the absence of a defined ankle on a person - whereby the calf of the leg merges directly into the foot. The calf appears to replace the ankle - hence the term 'cankle.'"
Gold's Gym has launched their Say No to Cankles campaign. This site is a hilarious must-see (yes, it's legit). Gold's offers advice for those suffering from cankles, such as walking or taking step classes. They also offer up fashion, such as avoid ankle straps and skinny jeans, and diet advice. This is so random!
