cement mixer 

A foul joke/prank performed. While perturbed, you take a dump inside a laundry machine dryer thats filled with your white laundry. You then run the dryer to 'mix the cement' and leave hardened skid marks on the victim's wardrobe.

I went in to grab my whites from the dryer and found that I had received a cement mixer.
