The key to being flabstinent is proper diet, exercise, and frankly, good genes.

flashsideways 

Similar to a flashback or flashforward but shows events that would transpire if a character's life would have turned out differently than what happened in the original timeline.

This concept was first started in the 6th season of the tv series Lost.

Guy1: "Man, imagine what my life would be like in a flashsideways timeline if Emily didn't break up with me?"

Guy2: "I know man, I know. Just let the tears out!"

Flassteen 

The most amazing person you will ever meet in your entire lifetime. Gorgeous is an understatement. She's insightful with her wise, witty and outgoing nature and she never lets anyone down. She is INCREDIBLY strong and will always follow through with her dreams. She's a phenomenal sister and all she does is give and love with her beautiful heart.

Person 1:
Duuuude I wish I could be flassteen like that!

Person 2:
I'm not even that Flassteen!

Blindly purchasing a product of similar quality on the sole preface that because it is more expensive than the general brand version.

Fapstidextrous 

The ability to jerk off with both hands, either at once or to switch off between hands. It's like being ambidextrous with your jerking off hands.

"Bro, I'm fapstidextrous. I can jerk off with both of my hands."
