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.
If your a hayder hussein you may like to kiss a friend called Emad and eat potatos all day long, it is not a bad thing because you are very huge that you can be a SUMO wrestler in the future!
Hayder is a very generous man, with high expectations, with good qualities and is loved by everyone on earth. The probability of becoming a Hayder is a 1 in 8 billion chance. So good luck!
