When you take water gun and fill it up with piss instead. Good for shattering the will and innocence of young children.
"Those little bastards across the street kept kicking their damn ball on to my lawn, so I got out the ol' Super Soaker piss gun and doused em'. Damn kids."

Get the piss gun mug.
1. When you're blue-balling, backed up with cum and ready to explode and just let some nut fly.

2. When you're ready to just whip your wang out and piss like there's no tomorrow.
Stacy: Alright Tom, I gotta go. Work just called me in.

Tom: Yo, you didn't finish giving me head, I mean, you have no clue what it's like walking around with a Loaded Piss Gun.

Stacy: Fine! (Gets on her knees and finishes sucking Tom off. Then Tom ejaculates all over her Applebee's work shirt)

Tom: Baby, you know I love you. Man, I need a cig.
