Bringing yourself to the edge of orgasm but not cumming repeatedly (8 hours personal best!), sometimes accompanied by captions or graphics related to the topic (see: goon-graphix.tumblr.com, goonluver.tumblr.com), lots of overlap with sissification/feminization/humiliation/fucking men and general porn addiction.
There's a certain mindset that you enter after a few edges which is fantastic.
