An octopussarian is an elderly male in his eighties who constantly keeps thinking of sex. If capable a man with this condition would desire to have physical sex as well. It is sometimes referred to as octopussarianism.
My grandad has been warned several times in the nursing home to stop pestering some of the elderly ladies for sex. it would appear that he's turned into an octopussarian.
