Can fads or trends propagate in non-human societies?

For example, let's say a Gorilla (or another social animal) sees another Gorilla getting attention from many females. Let's also assume the successful Gorilla has something unique about him - a limp or leaves in his hair. Could the Gorilla (or another social animal) decide to copy the other male in order to be more successful?

Are there any animals that will naturally copy another individual to appear more attractive?

Yes.  A small band of monkeys in Japanese started salting their food.   It started with one monkey washing her yams in salt water and others copying her (1965 Masao Kawai published in Primates)

People used to say- learned culture separated humans from the animals.  Then people started observing apes learning and passing culture/skills onto others and the next generation.  Like using tools (sticks to catch ants)
