If you're really really a tought guy and you have to express some biotches you ask someone if he has some 'magandr' for you.
In most cases he doesn't know how to react, because magandr is a fictive word.
He'll just ask you 'what?' and you encounter 'zzzssst' (sounds like the noise a fly creates) and place your fist somewhere it really really hurts.
A: "Hosch Magandr?" (do you have some magandr for me, honey?)
A: ZZZSST!!!!11! *punch*
