Thongs are in a way a wedgie allready...but just yank up sharply to make more, if its to give to yourself then buy a thong that to small for you then give yourself a shoulder wedgie.
What's The Most Painful Way To Give A Thong Wedgie?
Well, a thong is up your crack anyways, so you should just catch her when she's wearing normal panties. Then just grab the top of the panties and pull up until they rip.

Shame on you for wanting to cause pain to another person!!! If you cause pain to another person, assault charges could be filed. Keep your hands to yourself.
