Thankles are when you are massively fat and you surpass cankles ( when your so fat you cant see where there ankle fat begins and the calf fat ends) making it impossible to see where your thigh fat ends and your ankle fat begins.
You are so fat you have thankles.

Thick.Ass.Ankle

It *isn't* as thick as the "CANKLE", but it's not a skinny ankle. When you have thankles, you still have ankle-like definition unlike cankles when your calves run straight into your foot and you do NOT have an ankle or any ankle-like definition.

In order of skinniness, you have ankles, thankles, cankles
