Demon Semen 

A combination of a 44 oz. slushy from Speedway and a Monster or any energy drink. This mixture will not get you "high" but you will get a nice buzz from it. Invented on a summer day by two bored 16 year old dudes from Cleveland's west side.

Dude wanna make some demon semen and get our buzz on? Fuck yeah bro!!!

They love blood and gore... Or they might hate it. Idk what you like. Oh yeah, they certainly have some sort of love for some sort of spooky creature (in my case, it's cryptids... And dragons... And a bunch of other stuff). And if you're a memer... You've probably worn (or want to wear) an inflatable dinosaur costume.

Person One: Wh-what-

Person Two: *Proceeds to start screaming like a mad man*

Person One: *Also proceeds to start screaming like a terrified cat*
