Box Five 

A commonly-used term in the Drum Corps and Marching Band communities used to describe things as very very good.

Derived from the judging sheets of marching competitions in which the fifth box is the highest score for a specific section.

"That sandwich was box five, bro!"
"The band got a perfect score, because every single point was in box five"
"Your girlfriend was box five last night, if you know what i'm saying"

pack my box with five dozen liquor jugs 

A shorter sentence than "the quick brown fox jumped over the lazy dog" which uses every letter in the alphabet, a pangram. First mentioned in Mark Dunn's book Ella Minnow Pea.

There are 32 letters, only 6 are repeated, making this the shortest coherent pangram.

On wikipedia, they have a whole page devoted to pangrams. The only two that actually make any sense are "pack my box with five dozen liquor jugs" and "the quick brown fox jumped over the lazy dog." Besides these, there are many others that are used my different companies to test fonts.

Five Buck Box 

Created by Taco Bell in 2009, these taco-shaped laxatives provide old people a tasty alternative when it comes to their bathroom needs.

Instead of shotgunning a prune juice I ate a five buck box instead; needless to say I just destroyed that toilet.
