Thumb Rack

They're the dimples on the lower back where you can rest your thumbs when hitting it from behind.

Did you see that girl when she bent over to tie her shoes? Yeah she had a nice set of Thumb Racks.

Thumb Rack

The two dimples on the lower back that are used to rest your thumbs while hitting it from the back.

When Tiffany raised her arms at the concert you could see the dimples on her lower back. Alec said "That's a nice set of thumb racks"

John Thumb

Defined as the act of releasing one’s bowels in a manner where the shape of said excrement perfectly fits into the bottom of said toilet, plugging up the hole well enough to prevent successful flushing. Similar to the tale of the boy holding back a leaking wall with his thumb, this unintentionally shaped turd plug seats itself tight enough to hamper draining of thy marble throne.

Once I was finally able to push out that brown submarine from my ass, the dam turdpedo clogged my toilet so bad that my plumber said he doesn’t respond to JOHN THUMB service calls.
