I've just written a song about a tortilla. Well, it is more of a rap, really.

Behind the Groan

A Rap That Sounds Like a Wrap

Rap names a style of music, while “wrap” describes the food made by folding a tortilla around a filling. Because the two words sound alike, the speaker's correction shifts the song into a genre and the tortilla into a meal at the same time. Deliver the first sentence like a proud creative announcement. After a short pause, make the correction casually and avoid overpronouncing “rap.” The food meaning should arrive from the tortilla setup without needing the missing letter explained.
