A sappy fappy is a very sad fap in which a penis-owning person goes to jerk it but then proceeds to cry immediately afterwards because they feel shame from God (( or they just lost their partner and are sad they had to do that themselves )).

The King of the sappy fappy is Ben Harmon from AHS: Murder House who often cries after masturbating, thinking about his broken family.
Guy 1: Yeah man my girl just dumped me and now I don't know what I'm gonna do.

Guy 2: Bro, just go have a sappy fappy and cry it out.
