the mutual act between a man and a woman or two men ahhh, gay where sexual intercourse in the anal cavity is performed either due to the woman riding the metaphorical 'crimson river' or just for pure butt fucking pleasure between two men.
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...
A Shackteau is a humble, weather-beaten, structurally questionable shelter located in a spectacular or highly coveted place—Wales, Jackson Hole, Sun Valley, Crested Butte, coastal Maine, the Alps—where the building itself may be worth almost nothing, but the dirt, view, access, and mythology make it absurdly valuable.
In use:
Shackteâu - We thought it was an abandoned shed until the realtor called it a rare alpine Shackteâu with unobstructed views and listed it for $2 million.
