Rot

(Verb) You know when it's 5 p.m on a Sunday? You've got nothing planned out (because let's be real, if you didn't start doing something from the very beginning of your Sunday, the rest is probably gonna be the same) and you're just stuck there, either on your phone doom-scrolling or just wasting away in bed? Then you were rotting.
