Slang for sociopaths and psychopaths when they talk about feelings. When an individual has departed so far from what it means to be human and feel emotion, they lump it up into one word in order to simply the broad range of emotions, which in turn makes it easier for these individuals to detach themselves from them. This makes it easier for these type of people to dismiss their own accountability when they have emotional reactions, which usually involve harming others. Its likely these individuals also use drugs and alcohol to numb these feelings and to forget their actions, because of not dealing with their emotions in a safe and appropriate manner. If you know someone who uses the term the feels a lot, you need to recommend that they need to seek a psychiatrist. You may end up saving many lives by doing so.
