how did charley horse get its name

Quick Scoop

“Charley horse” most likely started as baseball slang in the late 1800s, but its exact origin is still uncertain.

The main theories

• A player may have been reminded of a lame horse named Charley, and the nickname stuck for the painful leg cramp.

• Another story says the term came from a baseball player’s nickname or a horse associated with a ballpark, then spread through the sport.

• Some sources say it may simply describe the awkward, stiff way an injured player walks, like a horse with a limp.

What we know for sure

The phrase was already in use by the 1880s, especially in baseball circles, and it referred to a sudden leg cramp or muscle spasm.

Bottom line

Nobody can say with complete certainty which story is true, but the strongest evidence points to an old baseball-origin term that spread into everyday English.
