A style of image instructing the viewer to roll a die and perform the sexual task listed for the resulting number (typically solo masturbation but variations for multiple participants exist). The format originated on image boards such as 4chan where, instead of rolling dice, participants would use the last few numbers of their poster ID to determine their result.

Note that, while multiple websites using the name "FapRoulette" exist, this tag refers to the general concept and not a specific website.
