Sleage: Rage induced by sleep deprivation. Similar to "Hangery", but involving sleep.
"Dude, why are you so irritable today?"
"Sleage, man. The kids kept me up all night because they took car naps. I think I slept for 45 minutes during Sesame Street."
Origin: Basically my life for the last five years. I used to get super grumpy when I was hungry, but now I barely notice because I don't sleep much. Now Spart shoos me upstairs to take a nap on weekends because I'm snapping at the dishes for not washing themselves.
