Gut check was originally a tennis term to describe a player pausing a moment to think about what just happened by closely examining and possibly adjusting his racquet strings. Back in the day strings were made of cat gut, commonly refered to as gut. This usually occurred after a great shot by an opponent. As with so many terms it has become popular to describe something very different.
