Used often to describe fan games adding more (and often very unnecessary) phases to an otherwise finished boss fight. Derived from the Undertale fan game, "Last Breath", in which its sub-community makes absurd amounts of fan made phases that exaggerate sans' durability and endurance to the point that it is a joke.
"Dude lets make vs tricky phases 5 and 6."
"Ever heard of Last Breath Syndrome?"
"No."
"Search it up."
"Ever heard of Last Breath Syndrome?"
"No."

Used to reference an action or comment that someone has just made that is ignorant, misinformed, or otherwise just plain stupid.
Stupid guy: I believe that the war in Iraq is completely justified and agree completely with the United States' foreign policy in the Middle East.
You: Check yo breath, son! The US foreign policy shit is totally whack!
