starting to take a shit in a
public toilet when it's empty, but then someone else enters the toilets and you have to hold until they leave before you continue your business.
the term comes from the same fear and
loneliness felt by both those genuinely
lost at sea and those holding a shit in a public restroom
Steve-"bro you were in that toilet for ages! what was
the deal with that!?"
Dan-"
Ah man, i ended up adrift at sea, the fear i felt was
unbearable!"
Steve- " i'm so sorry that happened to you"
