Gaster

A mysterious figure talked about in the game UNDERTALE made by Toby Fox through entities called "Gaster Followers". Gaster Followers can only be obtained through getting certain numbers on an RNG system called "FUN value." The Gaster Followers will hint at what Gaster was and what he did. A hallway can appear in the Waterfall area if you have a FUN value of 66, but there is a 10% chance while have FUN value 66 that a mysterious door will appear. An entity is spotted when going through the door. It is highly speculated that this person might be Gaster, as when you interact with him, he plays a sped up and reversed version of Gaster's Theme

"Gaster? Who is that? I've never heard someone with that name before.."

Gutter Nurse

Typically, a women who works as a nurse but also parties and stays out late until the wee hours of the night. Substance abuse and affairs would be considered normal behaviour for a gutter nurse.

Jolene came back to my house last night at 3am and when to work at 6, pretty sure she’s a gutter nurse.

Gaster

A man who listens

But rarely speaks

Susie: Oh my full name? It's Susie Gaster-
Once upon a time, a LEGEND was whispered among shadows.
It was a LEGEND of HOPE.
It was a LEGEND of DREAMS.
It was a LEGEND of LIGHT.
It was a LEGEND of DARK.
This is the legend of DELTA RUNE
For millenia, LIGHT and DARK have lived in balance,
Bringing peace to the WORLD.
But if this harmony were to shatter...
a terrible calamity would occur.
The sky will run black with terror
And the land will crack with fear.
Then, her heart pounding...
The EARTH will draw her final breath.
Only then, shining with hope...
Three HEROES appear at WORLDS' edge.
A HUMAN,
A MONSTER,
And a PRINCE FROM THE DARK.
Only they can seal the fountains
And banish the ANGEL'S HEAVEN.
Only then will balance be restored,
And the WORLD saved from destruction.
Today, the FOUNTAIN OF DARKNESS-
The geyser that gives this land form-
Stands tall at the center of the kingdom.
But recently, another fountain has appeared on the horizon...
And with it, the balance of LIGHT and DARK begins to shift...

Gaster Bullshit

"Gaster Bullshit" is when a game has major fourth wall breaks, ARG links, hidden mysteries, or anything other elements that could be compared to W.D. Gaster. Also used for any sketchy shit going on in Deltarune that probably connects to him.

"I heard oneshot had a bunch of gaster bullshit so i had to give it a try"

"WHAT DO YOU MEAN THE KNIGHT HAS HOLES IN ITS HANDS??? THIS IS GASTER BULLSHIT BRO"
