If this is a "natural arm position" - his arm is at 45 degrees below horizontal and his wrist is actually bent downwards as if he's making a traditional homophobic gesture - then I don't know what the term means anymore.

I’m not prepared to supply the video I have seen but when you see the arm come down to meet the ball in the penalty area, deliberate or not, they are giving a penalty.
Mischievous? Did you actually read what I wrote? I am agreeing that it was a penalty, that his arm is not in a natural position. It was absolutely clear at the ground.
And you've got a bunch of replies already agreeing with you that I'm saying the opposite... I think some people read the name of the commenter and then decide whether to slag off or praise no matter what they actually say.
