When you are eating a girls pussy out and she is on her back and you lying on stomach usually, with your face in her pussy you wrap your arms up and around her legs from the outside to the inside and while eating her box you spread her pussy lips with index and forefinger, while inserting thumb#1 in upper pussy and thumb#2 in main pussy hole area, cxonstantly working and rubbing and thrusting into her until mayonnaise is pouring out on your face and you smile while she shakes and moans. Great job Casey B. from Idaho, you can eat some box real good..mmmmm
Casey was double thumbing a girl he met at the gym on his kitchen table when his old lady walked in and busted him with both thumbs and his tongue in her little pink pussy. Casey was in Big Trouble Mister, BIG TROUBLE, but the slut got double thumbed so she was good.

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.

Similar to the "Old Fashioned Thumb Around" (going up to someone with open arms as if to give a hug but then quickly inserting your dominant thumb inside their asshole after you wrap your arms around them), but instead using both thumbs.
"I gave my ex boss, Mary, the New Fashioned Double Thumb Around in the break room right before putting in my two weeks notice. I figured what is she gonna do, fire me?"
