when the fat of the thigh overlays the calf and the ankle. There's variation in the leg.(Thigh-Ankle)
you walk into bar and meet a pretty face. Ya go home with this chick, and slide your hand over her whole leg, noticing no variation. You immediately turn blue in the face and your brain shuts down as a self-defense mechanism. This phenomenon is noted not only by the pre-existence of a cankle, but the thigh is consistent as well, exhibiting no definition whatsoever. The knee usually appears lumpy or hidden too, she has a Thankle

When an extremely obese person's thigh fat is so out of hand that it appears to engulf the knee, bypass the shin and calf and ends up stopping at the ankles. Combination of "thigh" and "ankles".

Gabe: Hell yeah, how could I miss her. She's rocking some mean thankles.

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.

A combination of the words "thigh" and "ankle". A variation of cankles, thankles are the non-definite ending of the thigh and beginning of the ankle. Most common in fat guinea pigs.
