The supreme awesomenessachieved when a Splendifer (a tiny, rainbow and sparkly dinosaur that feeds off of awesomeness) has taken residence in your left nostril.
Friend one- "I hope you are splendiferous during your audition today!"
Friend two- "That Splendifer has enough awesomeness to live off of for months, but thanks anyway."
Splendiferous can be used in many different contexts. During sexual contact, when someone asks you how your day is going, or when you climax alone or with someone. It is also a good word to use when Harry Potter role playing. Sounds like your casting a spell.
