This is a name given to an arab pimp.Its ussually heard only in kuwait and it is not used that often due to the high ranking of it. Out of All my friend i only know one person who is called hayder, but most people choose not to because of all the super model chicks he has wanting to suck his dick he picks the ugly deformed ones. Those are called faye's, but thats another story.
Look at that hayder! dawgs with a thousand bitches! lets take one of them
