The Ultimate title given to someone who has completed the close-to-impossible run and jump computer game full of 8-bit references, "I Wanna Be The Guy." People who have earned the title "The guy" are the kings of the video game world, and have likely spent way too much time playing the game, but because of the sheer difficulty this game presents, they are still hailed as some of the most epic players who have ever existed
A: Hey, after spending three months on his computer, Mike just became the guy!
B: NO WAY!!! THATS INCREDIBLE!!!
A: Its amazing right? We're throwing him a giant party to celebrate the epicness!

B: =D

Get the That Guy mug.
A respectful but informal greeting to a man. A term used to show acknowledge to a man which is casual as is using the word "sir or mister" which is formal.
As Tom sees his buddy Jim at the bar, he greets him by saying "Hey guy, what's up?"

As Tom sees his boss at a meeting, he says "Good morning sir" instead of "guy" because "sir" is more formal.

.... pause for bewildered look
" THIS GUY!!!! " *pimp-ass smile *
- Walk out back & get your dick sucked.
