The button on the microwave that burns your pop corn so badly that it is inedible, while setting off the fire alarm in the process.
"Why is the smoke alarm going off?
"Popcorn button, man."
That lame-ass button on most people's microwave that claims it'll cook your popcorn but either ignites it or only pops two kernels.
Why tf did the manufacturers put that popcorn button there? It's so bad even the popcorn bags tell you not to use it.
