"the lice of a thousand camels can annoy the ass of someone who will hate me and has such short arms that he can't scratch it..." English Translation. (it's brilliant!, I shall be saying this to anyone annoys me today)
I know it as "May the lice of a thousand camels infest your crotch and your arms be too short to scratch it!" Or sometimes I have seen arm pits instead of crotch and lice as fleas.
