I thought those were called Donkey Dicks.
I’ve told this story before but it bears repeating. When I worked in the restaurant, we had a naive waitress (that’s what they were called back in the day), and a perverted cook. We had a special, Bagel Dogs, but on the inside special board he wrote Donkey Dicks. Well Amy didn’t know what it meant, so she was telling the customers that the special was Donkey Dicks. Hilarity ensued. Amy didn’t last very long.
