ploppelganger 

When your poop is so big it feels like you just went in to labor and birthed your own twin out of poop

Bro, I just shit so much, I created my ploppelganger.

Sloppelgänger 

Refers to someone who looks like one of your friends, but if they were 30 years older and had completely let themselves go.

Much like a version of Your team for doppelgangers, when you spot someone that looks like a fatter, hairier, and/or older version of your friend, you can then say you saw their "Sloppelgänger".

Dude 1: Yo Mike, totally saw your Sloppelgänger today on the subway. I'm pretty sure he was homeless...but it was like SAME FACE.

bloppelganger 

An anomoly that occurs when you type in a random word in the urban dictionary and it is a yet to be defined word.

In a sentence. "Oh man, I totally typed in dippygooper yesterday and nothing came up...what a bloppelganger!?!"

sloppelganger

When you get so drunk, a doppelganger of yourself comes out with the complete opposite intentions of your usual sober self.

I swear it wasn't me that fucked your grandma, it was my sloppelganger.

I'm getting so drunk tonight that my sloppelganger is coming out. I'm going to be the fucking Queen of England.
