Their reactions to any of the scary moments. Or rather, Ross losing his mind at every thing that's meant to be scary, regardless of whether or not it's already happened, which then causes Arin and Danny to freak out.
Danny: Did that say "MC Toilet?"
Arin: MC Toil-(Laughs)
Danny: MC Toilet, y'all!
(The Pig Monster they've already encountered peeks it's head through the doorway and gets stuck)
Ross: Guys there's some-AGH AAAAAGH AAAAAAAAAAAAA!
Arin: AH OH GOD OH FUCK! WHAT HAPPENED!?
Danny: AGH...fuck you!
Ross: It can't get in here, it's too big!
Arin: OH MY GOD, THE BOAR! AH, FUCK, IT'S THE PIG!
Danny: Dammit, dude, it's not scary at all, but you fucking losing your mind, three inches from my head! [...] God, Ross, don't fucking flail and scream like that.
Arin: Yeah. Your, like, foot touched me, and I was like "AAAAH!"
Danny: You caused like a domino chain of der.
Ross: I'm really sorry, I'm not faking this, I fucking hate scary games!
- Then there's their encounter(s) with the Sundel Bolong, a banshee-like ghost with glowing red eyes and long white hair.
Ross: Hey, you're near something.
Arin: All right! Okay!
Danny: What the fuck, dude!? Okay, that was-
(It screams in their face again)
All: AAAAAAAAGH! (Ross whimpers)
Danny: Stop! Stop going there!
Arin: I'm trying, I'm trying!
Ross: Quick, take a picture of it!
Danny: God DAMMIT, Arin! Uuuuugh! I hate this.
(Arin pulls out the camera again and walks forward, revealing no ghost)
Arin: (Nervously) Nobody here!
Ross: I think it's behind you.
(Arin turns around. It was. It screams again)
At the end of episode 7 Arin and Danny go to take a leak leaving Ross all alone. He entertains himself in various ways for the following four minutes. What sells it is Barry's disclaimer.
Barry: This is literally just four minutes of Ross amusing himself while Arin and Dan pee. Just so you know exactly what you're getting yourself into.
- And then Arin and Danny return.
*Door opens as Danny laughs*
Arin: —they fuck each other and there's another dick hanging down.
Ross: Guys, alright. You're in a room, you're surrounded, there's no way out, guys with guns everywhere. This is what you do. *Starts rapidly firing a toy gun complete with laser sound effects*
*Arin and Danny laugh* note
Arin: And then you die immediately.
Danny: You cracked the code, Ross.
