Some guy's real name. It's a valid string for a man of an Arabian/Middle Eastern name, having the first name Mohammed, the middle name Mohammed, and the surname (last name) Mohammed. Also the most popular boys name in the entire world when you use the first name only. Mohammed M. Mohammed would be the way to say it with the middle initial.
I met this 3-1/2 foot tall guy with a black beard and turban who calls himself Mohammed Mohammed Mohammed and I picked him up, cuddled him in my arms and felt the wiry hairs on his chin.
