Spotbagging 

A combination of "spotting" and "tea-bagging". I was at the gym watching a guy spotting for another guy who was doing bench presses. The guy who was doing the spotting was standing right over the face of the guy who was doing the bench presses. The term just seems self-evident.

Josh was trying for a new personal record on the bench press, but his spotter, Zack, was in a playful/sick mood. Before Josh's record set was finished, he'd become the victim of a spotbagging.

Shitbagging

When you take a shit in a bag then throw the bag at someone

When you are at a music festival and the performance is displeasing.

Mike "Have you still got that shit bag"
Sally "No, I chucked it at Gorillaz"
Mike "Nice, was it a direct hit?"
Sally "Yeh it was a perfect shitbagging, exploded on impact!"

shotbagging

The act of ejaculating in a plastic grocery bag and hitting a person in the face with it. If done correctly, the plastic bag should break.

After we all jizzed in our grocery bags, we headed out to do some drive by shotbagging, and we were able to get five people right in the face.
