The act of consuming an entire Four Loko while in the shower for the purpose of pre-gaming an event. Exiting the shower before the entire drink is consumed is strictly forbidden. Commonly performed before college football games and fraternity day-drinking events.
Example: "We only have 10 minutes to pre-game and get cleaned up. What are we going to do?"
"Shower loko."
"Shower loko."
