Use the Source, Luke

A programmer's joke meaning you should read the source code. It is also a Star Wars themed pun on Obi-Wan Kenobi's "Use the Force, Luke!"
A short form of this is UTSL.

"Most people who come here for help do know how to read the source code. In case they can't, I tell them what to do. If they can, though, what I usually say is 'Use the Source, Luke!'."

Counter Strike Source

A remake, using the Source graphics engine, of the highly popular game Counter Strike. The game is very controversial amongst gamers because hardcore players of the original Counter Strike refuse to acknowledge it because of the changes the development team made such as bigger hitboxes, lower powered weapons and the dirty AWP scope..

cite your sources

To ask someone how they know something to verify the accuracy. This makes fun of educational institutions that force you to always cite sources when you write a paper, but used in something much less formal.

Hey dude, I found out that she totally digs you.

How? Cite your sources!

Counter Strike: Source

An online FPS game that originated from Counter Strike (CS). Counter Strike: Source (CSS) is mainly a graphical update of the original with a new radar, buy menu, and a few maps thrown in. Many criticize the game for being "easier" due to vital spots on players made bigger though the game is still challenging and fun. The game is often looked down upon due to the steadily growing number of prepubecent boys with microphones and hackers. Only a fraction of the number of total players of the original CS, play CSS. Because of the smallish number of players, hacking and cheating isn't as bad of a problem on CSS as it is on CS. Its still recommended that you play with the microphone mute option enabled.

*NOTE* Playing CSS may lead to a broken computer or possibly an early death.
