Sinfest Pipeline

A pipeline in which one begins with relatively progressive views except for their dislike of transgender folks, and ends with alt-right or even fascist-esque views.

Originates from the comic artist Sinfest, who began as a trans-exclusionary radical feminist, and devolved into a neo-Nazi.

Guy 1: It feels like yesterday Sam was super progressive aside from his transphobia, but now he's so hateful!
Guy 2: Sounds like he went down the Sinfest Pipeline.

Dude 1: How does it fit down there?
Dude 2: I'm a monk.

Alaskan Pipeline

An unusual, and somewhat taboo way of making a dildo.
You shit in a cardboard box and put the shit in the freezer, and then use the shit as a dildo.
Typically used in bizarre versions of porn.

"Tom, why the fuck is there a cardboard box full of shit in the freezer?!"
"I'm making a couple of Alaskan Pipelines"
