the sound made when one falls into an acoustic drum kit
When the lead singer fell, everyone at the show heard the plaz.
Intentional mispelling of plz, or please. Rather than sounding polite, it tends to be placed at the end of derogatory phrases. I was first to use it, therefor you must pay me royalties whenever using it in your daily leet speak.
