I give the version I ones was told:
"Genetic drift is an evolutionary force, which reduces the genetic variation. It is completely random and does not necessarily lead to organisms become better adapted to the environment they live in. Genetic drift comes from the coincidences that occur when the genes to be passed from one generation to the next"
