So this is probably a silly question, but what is VWW? I know most of the acronyms, but not that one, and a quick google search + search of the forum turned up nothing helpful. Would anybody mind explaining? Thanks in advance!

VWW stands for Vertical Wall Warp

Here is a video by Lamblord explaining it: tl;dr: jump and saveload in a portal on an out of bound wall and you get warped upwards
