Going through an emotionally taxing day leaving one feeling hateful and mad. At the end of the day, having a masturbating session. Usually the content viewed during the fap involves fetish pron such as goth, latex, bondage, SM and other bizarre forms of pornography. The angry-fapper does not necessarily have to be an lover of these fetishes, but is driven to look at them because of his/her consternation and furiousness. Some angry-fappers choose to accompany their session with hardcore death/black/gothic metal.
OOOOHHH....Fucking Gianni stole my Dr. Pepper! I'm gonna home and angry fap to Dir en Grey.
