Pied Piper of Poo 

Someone who is followed around by a nasty smell. Or by an army of little turds.

Fleshy Pipeline 

The act of attaching multiple dicks and dildos to each other, extending the length for pleasure, only used among the dankest of faggots.

Yo, I had a fucking dope-ass orgy that used a Fleshy Pipeline at that college party.

Truffle Butter Pipeline 

When you mix shit and cum together very well to make truffle butter then you put it in a condom. After that you put it in the freezer and when it freezes you use it as a dildo.

I was going to make a Truffle Butter Pipeline, but I my shit was too watery

the piper

A mythological or fictional being that collects dues while playing the flute after an evening of heavy alcohol or drug use. Bringer of the hangover.

(1) I woke up with a very bad headache, I felt nauseous, and I think I saw the piper in my kitchen. (2) On the way home from 111 Minna, I could hear the faint sound of his zampona and I knew I'd have to pay the piper.

Alt-Right Pipeline 

Used to describe the internet "pipeline" that slowly radicalizes typically young, white men into the ideology of the far/alt-right. It takes advantage of a process of desensitization through the YouTube recommendation algorithm. Slowly showing the viewer more and more radical content without themselves noticing much of a change.

One minute I was watching Pewdiepie and the next I was chanting Sieg Heil at the Richard Spencer rally. That Alt-Right Pipeline is no joke.
