When you listen to Coldplay and/or Genesis and and slap your nads with several partially wet, partially torn apart(cat-of-nine-tails esque) twizzlers. (Cherry flavors only). Also you can occasionally take you cat by tail only and use it to scratch your back to the rhythm of the music. If the cat resists smash against your own back several times before scratching.
My dad recently taught me how to perform a nad twizzlers...I sure love the aching.
