Grundleduce

An especially aggressive bowel movement, usually performed while performing an outdoor activity.

We were camping and I had to take a grundelduce. So I climbed up a tree, pulled down my pants, and screamed bloody murder. Grundleduce.

GrundleBundle

Essentially a Violent Tea-Bagging...

or my favourite turn of phrase "Like a dropkick, without the feet"
