The most common premise is that the name was a combination of bingo (the famed letters and numbers game) and Bambi, the captivating foal from the Walt Disney animated film. 

The name Bimbo first appears on a list of proposals founders drafted in 1943. It merited circling in competition with suggestions such as Pan Rex, Pan NSE (“Nutritivo, Sabroso y Económico”), Sabrosoy, Pan Lirio, Pan Nieve and Pan Azteca. 

Sometime later the founders found out that in colloquial Italian, children (“bambini”) were also called bimbo, a Hungarian word that means “cocoon” or “bud.” Even more surprising is that in China, a phoneme that sounds like “bimbo” means bread.
