Coolidge effect

increased sexual vigor when a human or nonhuman animal mates with multiple partners. The phenomenon is named for U.S. President Calvin Coolidge, alluding to a visit that he and his wife made to a farm where Mrs. Coolidge observed a rooster mating frequently. She allegedly asked the farmer to point this out to her husband, who is said to have replied “Same hen each time?”
