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.

Assertion: positive statement or declaration, often without support or reason: a mere assertion; an unwarranted assertion.

put the two together and you have Disingenuous Assertions so I'll dumb it down for you people

Disingenuous Assertions: pretty much lying to make someone look good and something that so infuriating that it makes soldiers want to punch reporters

I've had enough of your disingenuous assertions

Vegans Assumption Fallacy

A vegan must never assume that something is vegan unless and until it's confirmed to be vegan.

A vegan realised that he/she consumed a non-vegan product by failing to check the ingredients label, therefore falling prey to "Vegans Assumption Fallacy".
