Shekhir

Shekhir is the arabic word for snorting. The word on its own isn't an insult only the snorting sound itself is an Egyptian / Arabic insult, pronounced like CHHHHHH (like the grunting of a pig or a very great snort through the nose). In texting you will often come across it in its form 55555555 . Its a pretty bad insult and u can often expect a fight afterwards, exept u put an A7A afterwards, then it indicates that you are negativley surprised.

Its written 55555555 because the 5 looks like the arabic letter خ which indicates the sound CH
