READ UPDATES, CLIPPING DISCOVERED!

Have you ever been on one side of the map, staring at a gnome and think "I wish I could use that gnome to quickly get to the other side!" Well you're in luck, there just so happens to be a way to do that! Introducing, the Accelerated Gnome Boost!

Find any Gnome,you can find one behind the upstairs door in Home Base, which gives you the "Gnome from Home" achievment.

Use any part of the map to make the Gnome lie flat, like putting them on the edge of the steps and having him fall down.

Rotate the Gnome. If you want the most speed, rotate it so its pointy hat stabs you.
However, rotating diagonally can help for a more precise and diagonal movement.

Angle your camera down, the more down it is, the faster you go (To an extent, fully down is just vertical movement).

Update 1: I found a discovery! If you push yourself while on a ladder, you can still climb the ladder up and down while not being on it! You will still get off once you reach where the top or bottom of the ladder will be, though.

Update 2: You can also get pushed by or climb the ladders on scaffolding while holding themp, although I have found no practical uses for it, as AGB is faster, and the ladders can only push you horizontally. You can be ghost laddered by grabbing a ladder and moving it inside you. You can also be multi-laddered by repeatedly moving a ladder inside you.

Update 3: A use for ladders has been found, clipping! As Blazed_Yeti pointed out,

ive noticed the scaffolding can push you inside buildings, doesnt really do anything but was funny to see i could push myself into the structures.

This is true and works for both gnomes and scaffolding, though scaffolding is more prevalent in maps and much easier to clip with. I've found it works most reliably by pushing yourself into corners or weird geometry, like under the stairs in home base. The problem, most maps teleport you the moment you clip outside the map.
Although, I managed to clip inside the Public Facility by pushing myself into the door with the gnome positioned about 50° downwards. But, this is currently useless as none of the dirt comes off until you clean the outside.
