Octacular is a word both urban and dictionary-esque in its origin. The definition? Eight times spectacular. So not to be just thrown away casually when something is merely spectacular - oh no, octacular is strictly for when a matter or subject is eight times spectacular (which contrary to popular belief is an objective, tangible measurement and is in no way subjective). For those wishing to use octacular, be careful to ensure that what you are referring to is either spectacular exactly eight times over, or is sufficiently unspectacular to warrant a sarcastic usage. Prior to a serious use of octacular, the user should ensure that the subject is not either seven times spectacular (septacular) or nine times spectacular (nontacular) first.
The only thing known to be definitely octacular is the eight times spectacular, rectangular, octacular musteline - a brown furred mammal of exquisite good looks. Despite constant historical arguments over whether the creature was truly octacular throughout the ascent of mankind, scientific breakthroughs allowed a specific spectacularity-coefficient of 8.1337 to be applied to this musteline - a score supported by all available empirical evidence and thus verifying the animal's official octacularity status.
Octacular to the extreme! Who knows? Not me! But it is very Octacular Spectacular (MGMT album? NO - ANIMALS in the ANIMAL KINGDOM innit!), Oracular, mammals of Asia UNITE into the wonderful octacular musteline appendage mammal of Asia! YEAH! Man I'm tired.
