I'm interested in how player's outcries are regulated, which are directed at either the partner or opponents, also sideways, while playing or after the point was played. Would be better to have a link to an official document.
try to read the official regulation first. http://bwfbadminton.org/page.aspx?id=14914 http://bwfbadminton.org/page.aspx?id=14915 I heard somewhere you cannot shout and show fists/gestures to opponent. just forgot where
I think you can find the information in this document. I guess yelling/screaming/outcries/fistpumping are allowed, as long as it's not directly towards your opponent (=you aren't locking eyes to your opponent). I've seen plenty of matches on youtube where the umpire gave a warning regarding this subject.

Basically it is pretty specific that in play - you can shout during your own/partners shot but you can't use offensive language or shout fault or no shot. It would also be distraction if you were to shout when your opponent/s are hitting preparing. When the shuttlecock is not in play things get a lot more vague - what is clear is offensive language etc is not allowed still, the rest is just a matter of opinion because the nowhere is there specific guide lines on how you may celebrate a point. This is just covered by several cloaking statements like offensive manner or unsportsmanlike bla bla bla. Basically You could ask 20 folk if celebrating face to face or to the side whatever is offensive or unsportmanlike or not and You would just get different answers, making the idea/rules pretty much moot until defined.
There are so many opinions on what ought to be allowed. It's a good thing that the laws of badminton aren't too specific. Napoleon said that a country's Constitution should be short and obscure. The same should be true for the BWF's laws on this topic: If you try to make a law for each and every possible type of celebration, there will inevitably be something that isn't quite covered. Better to leave the umpires with some discretionary room to use in a given circumstance.
