Planting a Smirnoff Ice in a surprising and/or funny location. The Smirnoff Ice cannot be in a expected location otherwise the victim has the right to appeal the icing.
The victim who discovers the ice then has to get on one knee and down the ice. However if the victim carries an ice for protection (like a condom) then it turns into a counter ice and the perpetrator then has to down his own ice.
At the workplace, you are plotting icing a bro. You hide a convenient ice in a draw so when your colleague goes to open his draw for a pencil he discovers an ice. He is very surprised and a crowd of perpetrators who plotted the ice gather round. He stands up, gets on one knee and downs his ice since he doesn't carry a protective ice.
