grundle gnome

The tiny creatures that knit your grundle fur to your ballsack hair when you're seated. When you stand the hair rips apart. Ouch!!!

Whilst watching the football game the grundle gnomes visited me, and now both grundle and bag are sore.

grundle-cam

An all too common porn camera angle, where the camera pushes in for a close up, and captures only the man's sack and taint; and is often a result of poor camera work during the missionary position.

Dude, i was pulling off a good one last night until i got some grundle-cam. That shit was devastating. It set me back like five minutes.
