How Much is a Buttload?

I was in the grocery store the other day when I overheard this guy ask his freind, "How many beers do we want to get?" His friend responded with the phrase, let's just say,"A Buttload!" That made me think, how much is a buttload?

I know that we would all agree that one or two beers certainly isn't a buttload. I also know MOST of us would agree that 100 beers is a buttload. So, if I have 100 beers and I take one away, do I still have a buttload? Of course. What if I take another beer? Yep. If I keep taking away beers, eventually I will be down to a single beer. Which we have already determined is NOT a buttload. So, again I ask, "How much is a buttload?"

Well it turns out that this is what is known as the sorites paradox (from Greek: σωρείτης sōreitēs, meaning "heaped up") which is a paradox that arises from vague predicates. Well, as most of you know, I’m just not here to ask the important questions, but to get you the answers you need.

And that answer is the "Set a Fixed Boundary" theory of quantifying a vague predicate. Don't be bringing your Supervaluationism or Epistemicism theories up in here or I'll slap that scientific calculator out of your hand, punk ... Anyhow, the English Oxford Dictionary defines a "butt-load" as a unit of measure equal to "about six seams", which amounts to roughly 450 gallons or 4800 beers. Unfortunately, that number just doesn't work in the real world.

Now I'm right back where I started and so I am forced to turn to you, valued reader, for your advice. "How much is a buttload?" and how did you arrive at that number?
