I was lucky, the guys on my basketball team called me Horse. My buddy wasn't so lucky, his was Turtle.
There was a guy on the wrestling team when I was in high school - he had a twin - The one twin had no nickname the other - same as yours - Horse
 
I've had several in my lifetime. Lurch was one. The Terminator at one job (I had a pair of black Oakley glasses reminiscent of the T-800's in the movies). Too-Tall at another job.
 
I had two nicknames in my teens and college. My teen friends called me “Crutch” indicating that I had s third leg. In college, they often called me “jaybird” because I was always naked when alone in my room and of course people always came to visit.
