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".
Brett: Hey, Did you see that woman standing in the buffet line?
A bottom rung of society shit job, little pay, and you get no respect for doing it, but someone has to do it, and it sucks ass when it's you.
"Steve has such a shitty job as a garbage man."
"Yeah, it's a Thankless Job, but someones gotta do it, you know without garbage men and women we'd have trash buildup everywhere."
"Yeah, thats true......wanna go laugh at him since our jobs are better, and his is crap?"
"You know it."
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.
