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.”

FapJack 

A card game based on the card game "Blackjack" where players fap instead of wagering cash.

Rules:
1. Dealer begins a hand by dealing 2 cards to each player, including themselves. All cards are visible to all players, except the dealer's first card. (Dealer does know value of their first card.)
3. Players choose to "Hit" (dealt another card) or "Stand" (hold with cards they have.)
4. Hands adding up to more than 21 "bust", and loose that round. (A = 1 or 11, J, Q & K = 10, all other are their given value.)
5. Dealers must "hit" if their hand is below 17, or "stand" if equal or above.
6. If dealer gets "blackjack" (is dealt 21 on initial deal of a hand) or has highest hand, all players lose that hand.
7. Player with the highest hand, after all other have busted or chosen to stand, wins the round. (Multiple players can win round with a tie.)
8. Dealer chooses penalty (duration & intensity of faps) when players lose a hand.
9. Players that cum are out of the game.
10. Players that get "blackjack" (21 on first deal of a hand) earn a "rest" point they can later redeem to op-out of a given penalty.
11. If dealer busts, dealer removes an article of clothing and/or does something incrementally more sexually arousing for remaining players than dealer's last bust.
12. Last player that didn't cum, wins. (Alt.: Players that survive preset number of rounds win.)
13. Dealer will "finish" winner off (make player cum) in the way advertised to players before start of game.

Cleaving the buttocks in twain. Similar to a danza slap right along the buttcrack.
