Shelfie 

The act of "shelving" an MDMA pill by inserting it halfway into the anus, then taking a photo of said pill while it is still poking out from the anus before fully pushing it in. Usually followed by posting the resulting photo on social networks to show how hip you are with the drug scene.

Clara: "Lets get these pills up our arses and hit the clubs!"
Ned: "Just one moment while I take a shelfie for the facebook!"
