'Pop' could be...

'Pop...'  that was the name  Peter called Pepito
he had a condition, and it made him kinda lethal
See, each time Pepito would eat a burrito
it was like a maddening gluttonous  obsession
which caused him to devour one after another in succession

then, in a matter of hours... is all it would take
Peter would ask the lord "bless him" before his 'break'
but Pepito never seemed to learn his lesson
and so would be this natural progression his ass would start
poor ole Pepito would clutch his heart, let out a scream and fart...

PPLLLOOO...POP!!! BLOOOOOSSHHH, POP POP!!!
alas, he was so gassed he made his POP  an ART!!  L.O.L.
