look up any word, like guncle:
 
1.
This word is from the word turd which also means crap, therefore turdie is similar to the word crappy.
This meat is turdie.

Meaning; This meat is not to the highest quality.

The immature brother of the selfie.

Instead of taking a picture of one's self, a turdie is a picture taken of the fresh pile of shit residing in the toilet immediately after taking a steamy dump. For maximum effectiveness, turdies are preferably taken before the wiping stage has been reached.

Where selfies are typically taken by females, turdies are commonly taken by males to show off the sheer mass and beauty of their excrement, while providing substantial evidence that they are, in fact, a real man. Turdies are also typically shared via more private picture-sharing services like Snapchat.
I really hate it when people post selfies online. From now on, I will respond with a turdie to show my disapproval.
