i call it the zip. basically, if in a correct position you slide into an enemy, you will be zipped together forward. very weird and works 1/5 of the time.

video of me doing it.

another way to do it if you slide into an enemy's head. (sometimes an enemy is right next to a table, so you can just slide on the table)

bruh i have a video of that on my channel like a week ago

btw its posted on july 23

ahem, i knew the glitch since wayy back, it wasont really working out for me. note that this video is posted on july 19

It doesn't really matter who found it first. An appropriate name would be "physics launch" however, as it seems to be caused by physics interactions by Humanoids (character models).
