When a girl puts on a strap-on penis and anally penetrates a man with shaggy hair. It's called Reverse Rick Moranis for the reversal of sex roles, the shaggy hair which provides the girl with something to hold onto, and the high pitch of the mans voice after the act (similar to Rick Moranis' voice all the time).
Scott: Man, Nick you don't sound too good.
Nick: It was Katie's birthday, so I let her Reverse Rick Moranis me.
