A Butt Load Means 491 Liters

Asks Merriam-Webster:

Well, the quote is “Kobe, how my ass taste?” and I read it in the New Yorker, if such a thing is to be believed. But now I am even more shocked by the fact that I did not know the official liquid capacity of one of these “butts,” which according to 14th-century booze makers was:

A measure equal to 108 imperial gallons (491 liters).

So every time I have used “butt load” in my life I have been not just crass but exaggerating.
