A short amount of time, be it hours or days, in which you avoid life by falling back into a bad habit and avoid confronting it by telling people you're "relaxing" in your room, when really you're hiding from reality.
"ManCaleb won't come out of his room, says he's got a lot of homework this weekend"
"Nah man, it's just his relapsation time, he's watching all of The West Wing in two days"
