A special time (scheduled or non-scheduled) in a person's day/week where they celebrate by pleasuring themselves, normally in front of a PC.
1. I can't believe Stacy Henry just kissed and pushed-up against me! When I get home, it's FAP-TIME!
2. I need to hurry up with my research, Mike is coming home soon, and saving all of this info is seriously cutting-in on my fap-time.
3. Janice, when you're done with your fap-time, could you wipe off the chair in the computer room? The last fap-time you had made the chair look like a bird-bath.
When one places their favorite and most cherished pornographic content into a time capsule, buries it and 10 years later digs it up and masturbates to it again.
"Dude do you rememberthat time fapsule I made in 8th grade?"
"Yeah."
"My dog Rocko just dug it up, I guess there's no point in waiting now."
