The act of rubbing and inserting your thumb in a girls ass while engaging in doggystyle sex to gage her interest in anal...
I wasn't sure if she was up for anal so i gave her the exploratory thumb to find out if she was down
This guy was made famous around the web after he got pictured looking literally like a thumb.
This is actually amazing, just google image it.
Used sometimes when one of your friend looks like him on a picture, or to describe any fat bold guy.
Never heard of the human thumb? Check him out, this guy's awesome.
Haha you look like the human thumb on this picture!

The condition when the left thumb becomes irritated after playing to many games of super smash bros on n64. Three starts in a row at 11 stock is the number of games where smash thumb sets in, as noted by a Cumberland, RI doctor's son. Especially evident in players who push up to jump instead of using the 'c' buttons. Does not happen with ssbm or ssbb because of the less abrasive gamecube and wii joysticks. Some gay kids use batting gloves to help avoid smash thumb.
Booty and Big Gay Al could not be defeated by the team of LG and Snots because Snots starting bitching about smash thumb so Bird Man had to play, but no one was going to beat that damn incumbent team with kirby out there, not without G-Rod anyway.

Repeatedly going back to a word you defined on Urban Dictionary and clicking the thumbs up icon to inflate the popularity of your word. Like shaking it out at a urinal after a nice piss, you're entitled to one or two shakes, but not 45.
I define slut slam on Urban Dictionary. I think it is hilarious, but it gets no traffic or a few thumbs down, so I keep coming back to UD and give my word some thumbs upflation.
