more than an assload but still less than a fuckton.

Many, as in, more than a few in quantity.

Shitloads is "LONG" for lots.

A corruption of the term "shipload" of antiquity, as described the massive cargoes brought into harbor by sea-faring ships. Through association to the perjorative "shit" (itself a corruption of "shite"), the terms "fuck load", "ass load", and "butt load" were all created, the user, unaware of the origins of the term, substituting one curse word interchangeably for another. Over time, the second half of the expression also came to be substituted, most often in cases where "ton" was inserted for "load", whilst still maintaining the previously-replaced derisories as variations of the newly-coined phrase.

In its "proper" form, the phrase would be hyphenated and expressed as a linkage between two words to describe a third, correlated concept (i.e. "shit-load")

10% more than you can carry at one time.

A term which defines a numerical value of 47. It is prime. Do not confuse the term with similar terms such as fuckton, assload, or baker's dozen. This is a shitload.

meaning quite a few, a bunch, a lot, very many, more than you care to be able to count, more than you can count; a widely used exaggeration of there being far too many of something ~ not to be confused with a boatload or a whole fucking bunch
