Disingenuous: lacking in frankness, candor, or sincerity; falsely or hypocritically

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

sucks to your assmar 

A phrase uttered to an inferior ally, just before you switch teams/abandon them. Originally from "Lord of the Flies" in reference to the fat kid piggy, and his asthma, which was always slowing him down.

Jim:"I don't think I can make it George, you'll have to carry me to safety"
George:"Sucks to your assmar. You're on your own!"
