we've been toilet papered

Is it proper English to say you've been "toilet papered?" Although I'm not sure about the grammar, I am sure about what happened to our yard. It seems that the Navajo softball all-stars have an annual tradition of toilet papering each other's yards. It's a rite of initiation reserved for squealing 10 year-olds who are up WAY past their bedtimes.

I had fallen asleep on the living room floor when I heard a loud thud on the door. It was a roll of toilet paper -- probably thrown by one of the pitchers. Below are a few snapshots of the damage :-)
