When has a batter done some shyt like this
Well, for one, Saves (and Post-Season Saves at that) are a whole different story. It's like a Walk-Off HR: ain't shyt happening because the game is over. Now of course stuff like that can carry over, but that doesn't happen all that much (unless we're talking about hitting ppl).
Pitchers celebrating is pretty exclusive to relievers (closers especially). You don't see starters going nuts like that after getting an out. Most of the time they celebrate more to themselves if it's a particularly big out, but nothing extravagant.
The whole Batter-Pitcher celebrating dynamic is fukked anyways. Batters really don't have a means of revenge, while pitchers do. I mean, a guy goes nuts on the mound after striking you out, only thing you can do is try and get a hit in your next at bat against him (which many times isn't til the next day, at minimum, because as I mentioned, it's largely relievers), while a pitcher can take his revenge out on his very next pitch. It's fukked up, but them's the breaks.
