Sewer Snake

A windy shit that looks like a snake that gets flushed into the public sewer system

Will Meeks: Look at this shit, Mike!
Mike King: Wow, bro, thats a nice sewer snake you gonna flush! Take a pic of that one.

Gooncher

When a girls vagina is so big it looks like a goonch catfish's mouth laying on it's side.

Will: Hey, check out this picture of my girls vagina, does it look big to you?
Mike: Wow, dude, your girl has a huge gooncher, be careful when eating that, it might eat back.
