1. The Mothman - The Mothman is some sort of fallen angel/demon/bird creature that terrorizes mankind. This may seem ridiculous, but there's a pretty convincing one-hour special on the History Channel that I had the misfortune of seeing as a youngster that put the fear of this creature into me. Worse than the History Channel special was the time that I actually saw the Mothman while driving home one fateful night. When I finally summoned the courage to return to the spot where I saw him the next day, I found a Mothman-shaped bush in the exact spot where I saw it the night before. No doubt this was placed there by the Mothman himself in a devious attempt to lull me into a false sense of security.
3. Going to the Braves game and being shown on the jumbotron during the "kiss cam" segment and you're sitting next to a girl who's a friend, but not your girlfriend, so it's awkward to kiss her, but everybody's egging you on and you've always had a thing for her so maybe this your chance, so you go in for the kiss, but she pulls away and it ruins your entire relationship - That one's pretty self-explanatory.
4. Nicki Minaj - 70% sure she's a man-eating robot.
5. Opossums - Those beady eyes, that matted fur, that nasty tail, that silent O... what a terrible little creature. The fear here mostly stems from the time that I leaned down to pet my cat Socks, who was eating out of his bowl on the porch outside, only to find that it wasn't Socks at all, but a vile, beady-eyed marsupial with gnashing teeth and a black heart. (Yep. Opossums are marsupials. You learned something new today.)
