No, mipira is refering to sports balls (football, baseball, basketball)

Ok but this can easily be used like a metaphor no? Whem there is nothing "sporty" going on. And with an insulting tone of voice? I mean, if I would say to a man in english... you have a small flag pole... wouldn't that obviously be seen as an insult refering to his male organ, unless of course he actually has a flag pole in his garden... just wondering if it would be understood as an insult.. for learning's sake of course :-)

More like goading or dissing...

Think sport as in football, netball, volleyball, softball etc.

That should be valid though.

'hamna mipira' is not accepted as a correct answer, but I think it should be.

Yes
