n; A cheap alcoholic drink that is usually done before any real drinking is to begin. 1 shot of Castillo rum is dropped into a glass of Miller Light. Before dropping the rum the person about the drink must salute the drink and recognize the fact that they are NOT going to be going down with the ship, but will rather ride the tides to an island of humiliation (and sickness) to live as a castaway until the next ship comes along.
Jordan wants to get really drunk tonight, so he wants to be the first castaway
The anatomy of a cast away begins when you roll off a "raft" of toilet paper and put it in a friends toilet prior to taking a shit. From then, take your shit. Try to land it on your "raft". If done successfully, your Shit will resemble Tom Hanks in the movie Cast Away. Precede to non-flushing.
I was at my friend Trey's house and left a cast away in his shitter.
