Funny-Scary. Usually used in the context of GTLive when Steph and/ or MatPat is trying to explain why they are playing a seemingly harmless game on SGF.
Example: Both: TGISGF! MatPat: Hello Internet and welcome to scary games Friday where today, we will be playing FNAF World.
Steph: It's really more of a spoopy game than a scary game though. Isn't it?
MatPat: It's still TGISGF.
