Fast Brain Slow Thumb Syndrome

The acceleration of typing speed but deceleration of the accuracy in the words , content and context while texting due to thumbs fatigue although thought flows are exponentially high. Also known as FBST syndrome.

I was texting this girl come over to my room but instead I got hit with Fast Brain Slow Thumb syndrome and wrote “Come Over my hoes” so I blew my chances.

Thumb Fuck

To be constantly on your phone texting or messaging non-stop.

Classmate: "Has anyone talked to her about the break up?"
Me: "Na. She's been thumb fucking her phone all day and won't talk to anyone."

Hershey Thumb

When your boss or co-worker sits around with their thumb up their ass all day doing nothing. Once it's time to go home they remove their thumb which the tip is brown, coated in doo doo, resembling a Hershey Kiss. Sometimes they have poor hygiene and toilet paper is stuck to it as well representing the niggly wiggly completing the appearance. In many cases of frequent laziness and constantly doing nothing the thumb will be permanently stained from the feces.

Hey Joseph you got another piece of candy I see you have one already? Nah Levi I been hiding in the back doing nothing as usual. My fingers are just stained and have the ol' Hershey Thumb now.

The Green Thumb

Throw some potting soil on the ground and while having coitus in the doggy style position with your partner they pretend to be gardening. When finished sprinkle some dirt on their bootyhole and place a seed in the dirt, then plunge the seed in with your thumb.

My boyfriend gave me the green thumb last night, and now I have a green bean growing out of my anus.
