sleep rot 

When one sleeps for excessive hours, the following day is consumed by this. Involves feeling crappy, overall laziness, and messy hair. Similar to hangover, but instead of too much alcohol, it is too much sleep.

Dude, is she hungover? She looks like crap.

No man, she slept too much last night. She's got the sleep rot.

Rotten sleep 

When the quality of your sleep is just awful. You toss and turn, wake and fall back to sleep a little, wake again, restless leg syndrome, cant breathe, have anxiety, continue to toss and turn, even try hot tea and hot showers... still toss and turn until its bright outside. Typically happens after consuming sugar or waking up after being drunk and not being able to go back to sleep.

Ron: im gonna blow a fucking bullet in my brain! Cant fucking sleep.. its Rotten sleep god damnit!

Sabrina: oh i slept like a rock, maybe should stop getting drunk at 6 pm and passing out, only to wake at 1257 am.. hehehehe, wouldnt have to worry about that there rotten sleep.
