Biggest Of All Time in referring to a shit. Poop that looks not only inhumanly possible, but also makes you want to show everyone in the house. Nautical references also apply, as it looks like you just shit a yacht.

Mom: "son you just shit a B.O.A.T."

Another word for Cunt. On a website known as the5thplace, swearing became a big problem. So a swearfilter was introduced in order to stop it. The word 'fuck' would be replaced with 'duck'. 'Shit' with 'ship', so 'cunt' became 'boat'. Many years later, with the filter gone, many people around the world now use the word 'boat' instead of cunt
Hey you stupid boat!
