Trollge Is a "fandom" that consists in people making videos or comics where a person "the troll" and some times even "the Derp" play the part of the protagonist in an event or doing various actions that end (mostly) up going very wrong like the troll becoming a monster/demon/entity, or a monster/demon/entity destroying a city/nation/the world or it can also end up being just simply the world exploding
I watched a trollge video it was very creepy
