Not to be confused with Legionairres Disease
Marines Disease(AKA MD), A condition/infection of the brain, Not life threatening(But to others maybe?) which causes the person to have a natural compulsion to harass and disturb others in many ways(Compulsive Name calling, stalking, pestering others etc), Effects can be very horrendous and can lead the victim to SUICIDE. If the victim stands up to him/herself or retaliates, The person with MD does not like it and therefore goes mad!.
People who suffer this condition who decide to undergo a military career for some reason turn out extremely sucsessful in the Marines. This is how this condition was named 'Marines Disease' and makes the Marines 'A force to be reckoned with'.
Most of the MD symptons have already been described above but doctors claim that MD sufferers have a 'Harassing Call' that is used when they harass thier pray, However it sounds like 'Ele Cuntay'(Sometimes Illay Cunfay). For example if thier victim was called John, The MD sufferer would say 'John Ele Cunthei' multiple times.
Marines: 'John ele cuntei, john ele cuntei, john ele cuntei, john ele cuntei'.
John: 'Damn, Im getting sick of being harassed by those Marines all the time!, At least im not suffering from marines disease!.'
