The Keemstar Effect 

It's when some no-name YouTuber gets popular through being on DramaAlert, or being shown on one of LeafyisHere's or Pyrocynical's videos.

Person 1: Did you hear that LtCorbis was featured on LeafyisHere?
Person 2: Must be the Keemstar Effect again, she's got 100k subscribers now.
