dunderball 

any non-computer game played during work hours to pass the time.
From the "The Office" episode "office olympics" - throwing paperclips into someone's coffee cup, bouncing a NERF football against the wall, taking bets on who will exit the elevator next, etc etc.

I'm bored and the server is down - you up for some Dunderball?

Dongerball

Not to be confused with the game dangerball. Dongerball is a game where you send a picture of your dong or your ball upclose and the person you send it to has to guess which one it is.

Her: hey wanna play dongerball
Him: what’s that?
Her: send me a pic of your dong or ball and I’ll guess what it is.
Him: okay

dangerball 

A game played using a small bouncy ball. 3 or me people must be confined in a small area. Then, with little or no light, each person takes it in turn to throw the ball as hard as possible into a wall or ceiling. If you don't get hit, you win. Repeat for jokes and cokes.

Yo Bill, you wanna play some dangerball with me and Johsnon?

YEH MAN

dangerball 

A drinking game that is similar to beerpong, but has some dangerous twists. You have an extra cup that rests on top of the other cups (the dangercup) and when that cup is made your team has to take a shot of alcohol. There are also two dangerballs that rest on top of the cups that can get knocked in.

Guy1: Dude, I'm sick of beerpong
Guy2: Let's play some dangerball then
Guy1: That's dangerous
