The impact between the wrestler and the ground. If a wrestler is slammed particularly hard or falls from a great height, it’s said that he “took a hard bump.” A skilled wrestler will know how to land— usually flat on his back, to distribute the impact—so that he won’t suffer serious injury.
Fan #1: “I always get scared when Brock Lesnar suplexes the Undertaker.”
Fan #2: “Agreed. The Undertaker is too old to be taking that many bumps to the back of his head.”
