[Funny Topical Meme]

Off-topic: a branch of a forking path, that leads back to the main path.

[CreepiX]

Possible Geometry - an easy room with some corridors. 
Not-So-Possible Geometry - the same room, but harder and with warp lines to confuse player. 

[lol...ipops2]

Oral-May Whatever fits.
And now a veni vidi vici.
Great. the start
Why aren't your legs spike-proof? Easy.
East Berlin A branching path
The berlin wall/vIck The berlin wall is death, vIck is very hard.
TORI! The turnaround.
{End veni vidi vici}

Warp Dream, Warp Reality, Warp Nightmare - Any three rooms with warps.
Trespassing On Private Property - Firstly, in the beginning of the level, you can go into a room off of the main trail and see a room with many enemies and one trinket that you can access much later.
Up For A Challenge? - The first room in a set that will be a challenge, or a DTTHW joke. (You know, since you start by going up [or down])
I hope this helped a bit. No credit really needed.

I like this guy.

Do You Believe in Ghosts? A purplish room, obviously.
Little Jay A J-shaped room. Simple.
Bulletproof I wish I was. (enough with Radiohead references) However, a room that should be similar to that one in the Savior level with enemies popping out of a wall.

Easter egg: I'm continuing that FFFFFF project I was planning time ago, and in a lab room I put the Overdose-themed roomname 0.37 Feet From The Ground. I'm still scared about that [[STOP RUNNING]] thing.

Bulletproof is the same reference to TF2

anyways

Rupture

flip up and down then drop off then flip the spikes then go right then left then up then left then down then go to next room

[Quattro]

Bulletproof is the same reference to Team Fortress 2.

Oh, I just hate that game. Mine was a reference to La Roux's song.

Laber Bris A Kygo song, actually. I imagine it as a particular room with a left-to-right room containing a challenge with two mechanics blended within. For example, gravity lines and disappearing platforms.
Until The Dawn Rises A corridor with a shattered ceiling that leads to open space.

[Duckman50001]

The Vault - A direct-mode room made with the Polar Dimension tiles and yellow Warp Zone tiles (Has a trinket)
Love Bird - A room that you rescue then come back later to rescue 
The Great Maze Of V - Pretty self expanatory

[Tainy]

Tee Hee I'm Sorry/Oh Wait No Not Really - Two consecutive rooms after a hard room or set of hard rooms, the first having no obstacles, and the next continuing the hard rooms.
(It's lines from a song I really like, Click Bait by S3RL.)

[AVVVVVVGuy]

Ultimate Spamming - A room with "aaaaaaaa" roomtext obscuring your view.
Don't Take the Cyanide - A room with cyan spiky platforms.

[Shadeblast]

Bulletproof is the same reference to TF2

anyways

Moving End

[Bruce Michez]

Goldfish Don't Bounce - for an orange room with vertical enemies crossing a horizontal gravity line.
