The Kiddie Pick
  When you're by yourself and you uninhibitedly twist your forefinger into
  your nostril with childlike joy and freedom.  And the best part is,
  there's no time limit!

Camouflaged Kiddie Pick
  When, in the presence of other people, you wrap your forefinger in a
  tissue, then thrust it in deep and hold back the smile.

Fake Nose Scratch
  When you make believe you've got an itch but you're really trolling the
  nostril edge for stray boogers.

Making A Meal Out Of It
  You do it so furiously, and for so long, you're probably entitled to
  dessert.

Surprise Pickings
  When a sneeze or laugh causes snot to come hurtling out of your nose, and
  you have to gracefully clean it off your shirt.

Autopick
  The kind you do in a car, when no one's looking.

Pick Your Brains
  Done in private, this is the one where your finger goes in so far, it
  passes the septum.

Pick And Save
  When you have to pick it quickly, just when someone looks away, and then
  you pocket the snot so they don't catch on to what you did.

Pick And Roll
  No explanation needed.

Pick And Flick
  Ditto.

Pick And Stick
  You wanted it to be a "Pick and Flick," but it stubbornly clings to your
  fingertip.

Paydirt
  The kind where you remove a piece of snot so big, it improves your
  breathing by 90%.
