The area in affected female legs where the calf meets the foot in an abrupt, nontapering terminus; medical cause: adipose tissue surrounding the soleus tendon, probably congenital, worsened by weight gain and improved in appearance only by boots. From the English "calf" meaning wide portion of the lower leg, and "ankle" meaning slender joint of leg with foot.
If I didn't have cankles, I might be able to wear those Prada loafers with my capri pants.
Noun. A sight common among the morbidly obese. The point at which one is so obese that there is no thinning of the leg between the calf and the ankle, which creates a sense of fusion between the two. Consequently "Cankle" comes from the fusion of CAlf and aNKLE.
