The act of sticking your thumb up your ass and using the resultant shit thumb to tack a picture of a hot womans face over some random skanks face prior to having missionary style sex with her; this is preferred if the young lass is buck toothed, has a mustache, chronic halitosis or is just plain fugly.
I picked up this troll at the library, took her back to my place, tore a pic of Reese Witherspoon from the latest cover of People magazine, administered the rusty thumbtack and proceeded to mount that ass a'la hucklebuck style, dropped a nut on her breastseses and got the fuck out....have not seen her since....good times
