Green’s Dictionary of Slang

pongelo n.

also pong, ponge, pongello, pongellorum, pongelow
[ety. unknown; given origins of the word in the Indian Army there may be a link to the Tamil festival of Pongol, the festival of the new rice, and which if so may pun on boiled adj. (1), since pongal means ‘boiled’, albeit of rice]
