Shaniac

A person who is a fan of the series BuzzFeed unsolved on YouTube and doesn't believe in ghosts, spirits, demons...
The names origin is from the co-host Shane Madej, which is the skeptic in the show. (So call him a Maniac for taunting spirits to kill him.)

Ryan: *shows potential evidence for ghosts*
Person in the comments:. Nah, it's just very windy #shaniac
