Eepenheimer 

It is a joke that came from a Youtuber named Flamingo. (A primarily Roblox Youtuber.) Normally these phrases can be made in anyway. Like Yeetenheimer, or Killenheimer. Normally this Roblox Group may have some furry elements and the audience is normally 8-15 (Very Immature.)

"You are just a stupid ass Eepenheimer."

Yeetenheimer!1!!1!!
IMMA KILLENHEIMER!!!!
