This particular version tends to result in a My God, What Have I Done? moment as the ranter calms down and realizes they chewed out an innocent or even extremely well-meaning person (who is now, understandably, extremely hurt). They may have given Unwanted Assistance after seeing they've had a bad day. In these cases, the person had nothing to do with the rest of the stuff that ticked the person off, they just happened to say the wrong thing at the wrong time, setting off a powderkeg of pent up stress and emotion. Both in real life and fiction, the target of the resulting explosion of anger is often someone completely innocent. Everyone's had a really bad day at some point and has had to struggle (often unsuccessfully) against exploding over something fairly minor. This can be an example of Truth in Television. If the others are feeling particularly jerkish, then then they may deliberately do such things to push the character over the edge, then stand back and watch said character get lectured for the ensuring explosion. If this happens in a large political scale, it can look like a Silly Reason for War.
