Top Shelf 

When shelfing (or shelving- i.e inserting something in your rectum, usually ecstasy for increased absorption rate) the way that one knows they have done so correctly.
Go in with your finger and curl it back over- place it on the top shelf.

Dude: Here man shelf this.

Other Dude: ...... I've never done that before.......how do i, you know, know its in the right spot.

Dude: Up and over- top shelf. (Whilst doing up and over motion with index finger.)

elf on the shelf 

A very creepy tradition perpetrated by adults around children of young ages. The legend goes that the elf on the shelf is hidden and watches the children and then reports back to Santa with his findings. In a nutshell, this is Santa's NSA, with less phone taps. Although this may seem a jocular activity to keep your offspring in line, it actually is a pervy way to watch over your kids, using the threat of not receiving gifts during the holiday season. The adult version of this practice is not-so-subtly named whore in a drawer

Dad 1: Hey Rick did you hide the elf on the shelf for little bobby and Susie this year?
Dad 2: Hell yeah I did, Arty. I put it in the bathroom so my kids will shit bricks.

Mid-shelf

A magazine that isn't pornographic enough to be top-shelf, but is still sold more or less with the single purpose of providing material for masturbation. Often contain women who believe themselves to be famous for something other than their breasts.

My girlfriend doesn't like me buying porn, so I just get the mid-shelf magazines and pretend it's for the gadget reviews.

Since Gemma Atkinson left Hollyoaks, her entire career has been posing for mid-shelf magazines.
