The feeling of guilt when you have finished masturbating over an ugly person.
Also applying to masturbation over ugly pornographic material (e.g. fat woman).
When you are feeling seriously horny and you think it is acceptable to choose a random person to masturbate over. Either whilst looking at one of their photographs or texting/ chatting to them online. Only to realize shortly after you've exploded that they are fuck ugly, and you've just made the biggest mistake of your life. You have fallen victim to a 'guilt wank'.
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.

Shackteâu - We thought it was an abandoned shed until the realtor called it a rare alpine Shackteâu with unobstructed views and listed it for $2million.
