De Velize

The act of placing a venomous snake in the top tank of one's toilet, in anticipation of a house sitter upper decking it, the expressed purpose of which is to cause their immediate demise as a result of a vicious strike to their hoop.

My house-sitter should never have threatened to upper deck my toilet, because I took proactive measures and De Velized him. The paramedics thought it was hilarious.
