Kamina Assumption 

noun; an assumption that any situation or problem, even if it is logically insurmountable, can be resolved by sheer passion or force of will.

This phrase was inspired by the character Kamina from the anime Tengen Toppa Gurren Lagann, who has a tendency to conquer insurmountable obstacles by his fiery, manly passion; a force that is approximately equal to the red-hot plasma of a thousand suns molded into the shape of mustangs and panthers.

Kevin: Look, I know that we only have half a tank of gas and no cash, but it's my dream to finish this cross-country road trip and I know we'll do it somehow!

Me: Considering that we're still in Wyoming, I'd say you're making a dangerous Kamina Assumption.
