When the crackling noise of rice krispies is being heard by everyone in a random room, its called a snazzle-pop.
Sometimes, it will make a large popping sound and end with a sizzling stop
Fiona: I was at Tx. History when a snazzle-pop went off.
Brad: Ewww, your fart made a snazzle-pop
John: I Love the sound of snazzle-pops
Gus: I love snazzle-pop
