When a guy and a girl like each other a lot and they go off and either make out, have sex, hand jobs, or do anything sexual.
Mildred: "Miranda and Randy are totally wiggling right now."
Scott: "WHAT! I heard the same thing!"
Mildred: "The other day I saw them wiggling also."

Wiggling
A Masterbation technique used in place of stroking off. First you remove all your clothes and lie prone on the bed. Then you rock left and right while using the surface to hold pressure on your sword. Just prior to climax roll into the supine position for sweet release or lateral recumbant if you prefer.
