thumbhorn 

v: when a man uses his thumb to help ease his limp penis into a vagina -- this act is often performed while drunk and resembles the operation of a shoehorn fitting a foot into a shoe

I drank 37 beers last night and there was no chance I was going to get hard. I definitely had to thumbhorn the bitch.

thumbfart 

A thumbfart is when you misspell a word in a tweet or text message and send it out without realizing it. Similar to a brainfart when you speak. It's a word created by Dustin Zito of Real World Las Vegas on MTV. Season 25.

"I worked out like a beast today. Tonight I'm gonna need a message!" This is a thumbfart. The word should have been "massage" but "message" was used and sent by mistake.
