A subejective rejection mood. It's one of those emotional times (mostly found in guys) where you don't want to be subjectively nice to a certain person. Everyone can notice the mood, it's the mood between aggetated and pissed off. Another way to say Tanked Off is a boys time of month.
Charile came into work aggetated that his mother kicked him out.
His girlfriend comes in and breaks up with him currently making him Tanked Off. he rufuses to do his daily activities and work.
At the end of the day Charle's boss fires him. Now he's pissed off.
