Fork Tuning 

The act of sounding (the practice of inserting plastic or metal rods into yours or someone else's urethra) while edging (getting seconds away from climax and stopping, waiting for a few more seconds then starting again) then when you finish your edge you take out the rods and the flood gates open.
