horrorgasm 

When something is so disgusting that you gain sick pleasure from it or get turned on because it's just so gross.
Like when the perky cheerleader in the horror film gets her head chopped in half and blood and gore squirts everywhere, and you feel that rush-type-thing as you scream. Or when you're reading a really terrifying story and you're like squirming around in anticipation of what happens next and all giddy and scared.
Basically getting excited by something creepy.

"This is so nasty it's awesome! I'm totally going to have a horrorgasm if the vampire tears out that dude's jugular!"

Horrorgasm 

An event so scary you feel a strong sexual arousal afterward. These tend to be very strong and addictive.

Hoborgasm

When a hobo realizes that he will have a meal to eat in the near future. Or when a hobo climax's during a hoborgy.

Reggie the hobo had a hoborgasm the other day when he got invited to a Thanksgiving dinner. He got invited by having a real orgasm with the dinner host.

horrorgram 

A video on social media that would be place under the horror genre of movies.

My friend sent me a Snapchat with a jump scare at the end. It was a total horrorgram.
