Translation of "inept" into Serbian

The only thing you should remember is that everyone else is either reckless or inept.

Jednu stvar zapamti, a to je da su svi ostali nemarni ili nesposobni.

Fortunately for us, the crematorium did a completely inept job.

Srećom po nas, krematorijum je nepodesno odradio posao.

So... tell her I was inept, or coarse or beyond ugly.

Recite joj onda da sam neprikladan, grub ili jako ružan.
