A kind of hot spiced rum cocktail, made with eggs.Around this time at a restaurant, I heard an adult order a ‘Tom and Jerry’ from the bar and I wondered if the drink was named after the human Tom and Jerry or the animal Tom and Jerry.
Origin
Early 19th century (also as a verb in the sense 'drink and behave riotously'): with allusion to the chief characters in Pierce Egan's Life in London (1821).
