To do a small poop, no bigger than a grape. Such pooplet comes out in multiples and is never a single entity. Therefore pooplets are never alone. If on the rare occasion you do a single pooplet, it is referred to as a pooplia.
After blowing up a balloon, it is the act of releasing the balloon from your grip and letting it flyaround the room deflating itself...hence making the "Ploogled" sound.

Cort: "Oh no, I let go"
Jayme: "Shit, you ploogled it!"
Balloon: "PPFFFBBBBFFSHHH"
Jayme: Ha, its ploogled.
