This started in response to a blog by some loser that I can't remember the name of (iefingering, MT). He was always talking about strippers and more strippers and even more strippers. Also, he had some stripper girlfriend or some such and one tim he was talking about making ote with her and said something along the lines of, "...then I got to play with her (ie fingering)...". We added the 'j' just for fun.
