To Weigh Anchor in Poo Bay is another term to describe the plundering of an anus (male and or female) by some one who thinks they are a modern day
Black Beard.
This works best, whilst wearing a
pirate hat, or for the more extreme/adventurous "Weighing Anchor in Poo Bay" whilst having a parakeet on ones shoulder, which can end up in a very
sticky situation...
Mac: I totally "Weighed Anchor in Poo Bay"
last night! She loved it!
Ross: Sick! Did you try it with Becky's Parrot on your
shoulder!?
Mac: Hells yea! she got abit pissed about
the parrot shitting on her back though...
