The act of, rather than sticking your thumb in her ass while you're fucking her, you pull out, shove it in her ass, and plug her vagina with your thumb

A Thumb Bump is a fist bump with a thumbs up to finish it off. Originated on classic TV show Thunder in Paradise. Randolph "Hurricane" Spencer and Martin "Bru-dog" Brubaker would do a Thump Bump to celebrate a job well done.

When you text the same person over and over for a prolong period of time, you notice a change in your thumbs’ physical appearance. Typically you’ll notice the knuckle start to get a bit larger due to repeated movements required to do said texting. It’s also a sign of early stages of carpal tunnel syndrome.
I texted this chick while she was in the Bahamas for about 5 days, countless times everyday I noticed my buff thumbs starting to develop.
