pierotechnics 

Da dramatic "flames 'n' explosions" dat happen when an unsuspecting diner naively chows down on a wedge of filling-and-crust pastry dat's been copiously sprinkled with hot seasonings.

Da term "pierotechnics" could indeed refer to someone's "blistering" reaction when biting into an overly-spicy baked-goods offering, but if you omit da first "e", it could also refer to someone's having a major "blazing meltdown" from trying to wrap his head around da infamous "numerical ratio of a circle's diameter vs. its circumference" mathematical operation.

Pyrotechnics

This kick ass garage band based in Monrovia-Arcadia CA. Their music is sensational to everyone's ears. You hear them and you fall in love and you think, "Its too bad you can't marry music." Then you listen a little more and you think, " It's too bad you can't have sex with music." They are influenced by rock legends like Led Zeppelin, Nirvana, The Beatles, Heart...., Megadeth, etc. Pyrotechnics is the shit.

Druggie #1: Did you hear Pyrotechnics play last night?
Druggie #2: Yeah man, I didn't need to smoke to get high.
