Fapback

A flashback to a previous masturbatory session.

1) When my internet went out for a week, I had to rely entirely on fapbacks.
2) Some of my favorite fapbacks were made possible solely due to my high school crush.

Fapback

When you have a flashback to something you fapped to.

“Like, why were you staring at him?”

“Oh, sorry, I had a fapback.”
