[[caption-width-right:350:Damn, that's harsh!]]

The WeaponOfChoice for the BrattyHalfPint and {{Youngsters}}. Water Balloons may be used alongside [[BratsWithSlingshots slingshots]].

The contents will not always be water -- it could be jelly, ink, or something more... [[UrineTrouble foul]]. Either that or some jerk will bring out the hose.

Expect college science geeks and/or medical students with too much time on their hands to build a water balloon slingshot out of lab materials, or some other ridiculous contraption. They might also fill their water guns with liquid chemicals.

Wet T-shirts and swim suits may lead to SexySoakedShirt.

Compare BubbleGun.

Hilarity ensues and they later on begin using hoses, and a gigantic water-hose/water balloon combination, which eventually leads to the whole town ending up underwater.
