When you use the tears of someone as lube to masturbate with.

The best lube to improve your mood!
I broke up with Sarah and she started to cry, quickly I gathered her tears for a sorrow fap.

Get the sorrow fap mug.
When you're really depressed and you start to cry and fap at the same time, and you continue to fap even though you're crying.
I was really sad one night so I started looking at porn and was beginning to start sorrow-fapping till my girlfriend came in the room.
