The next day after smoking
marijuana the previous
night, one tends to feel very chill and
lazy about everything. A dumbover is the next step up, but sometimes you don't get a dumbover, just a chillover. If you have a dumbover, you usually have a chillover. If you have a chillover, you don't always have a dumbover.
-"I only smoked a bowl or two last
night before bed, so I have a chillover
today haha."
-"I didn't go to class
today because I had a chillover, so I just played FarmVille instead."
