So, a few thoughts from my background on these discussions.
In my opinion, the use of the phrase 'forward slip' only serves to cause confusion.
If you google forward slip aircraft, you will find an explanation of what it is and the difference between a forward slip and a sideslip. Pilots should be familiar with both terms and the difference between them. Admittedly, some posts here(including mine which have now been corrected) used the incorrect terminology(sideslip instead of forward slip).
Here is what the FAA has to say about it(if you scroll down)
