A word coined by the one they call Nunez after playing 'Minecraft: Xbox 360 Edition'. It's slowly becoming used by gamers alike.
Some examples of where this word is acceptable to be used is:
I. After great, but not excellent sex.
II. After finding out you aren't HIV positive after the sex.
III. When playing Minecraft for the Xbox 360 (it wasn't as good as I expected.)
IV. Having exactly 69% as a test mark. (Note that 69 is a hilarious number, however 69% is nothing to write home about. Hence why in this circumstance it's beast nuts.)
V. Seeing a great set of tits, but unfortunately ruining those $500 slacks.
Neckbeard #2: Yeah man, it was pretty beast nuts but it had its flaws.
