Thumbs In 

Rather than the thumbs up or thumbs down response to something, "thumbs in" denotes an inability to care less. While holding one thumb up and the other thumb down, you then bring both thumb gestures behind you and motion to place both thumbs "in" your ass.

I voted thumbs in last election.

Thumbs up if you're watching this in... 

What happens when a bunch of fucking idiots on Youtube think of a way to get thumbs up on a video from a year ago or more. It goes like this:

*Video from at least a year ago*

"LULOLOYULUOULZZZZZ TUMZ OOP IF YURZ wochin dis in 2012!!11111!11111111!"

Me: No, I'm listening to this in 1933.

"lulz hipstr fag"

"Thumbs up if you're watching this in 2012."

Me: Kill yourself.

(I have to include the title in the example so Thumbs up if you're watching this in...)

Thumbs up if you're listening to this in 2011 

A term youtube users will submit in the comment section of a video of any song that is older than a year to let everybody know that because they listen to older music, they are special. As a result, people who feel the same give them thumbs up as was the original intention of the comment.

(Comment on a Queen music video) "Thumbs up if you're listening to this in 2011" 151 thumbs up.

Thumb in a softie 

The action of inserting a flacid or semi flacid penis into ones sexual partner using a thumb or finger in an attempt to engage in coitus. The action is usually performed after the consumption of a considerable amount of alcohol and is regarded as a token effort at sexual intercourse.

"I was absolutely twatted and knew that there was no way that I could possibly perform, despite the fact that she was absolutely stunning and horny as a goat. I knew that if we didn't have sex she would be upset but I was drunk as a sailor. Therefore the only possible course of action was to thumb in a softie.

The first verse of the song "Smash Mouth" by "All Star"

"Somebody once told me the world was gonna roll me i aint the sharpest tool in the shed she was looking kind of dumb with her finger and her thumb in the shape on an l on her forehead."
Bob: "WHAT IS THIS?"
Sharyl: "GOD'S SINGING VOICE"
Bob: "AHHHHHHHHHHHHHH" *eyes melt out of head*
