Let me tell you, you don't have to be fat to have cankles. My wife has a very thin fantastic looking friend with cankles. My buddy dated her right out of college. All the girls were swimming in their bikinis one summer day and my friend said to "look at her body man" to which I replied "dude she's got cankles". Needless to say he was a little pissed off but that is a deal breaker for me.
