The Guitar Hero Challenge 

The Guitar Hero Challenge is doing a girl doggy style while trying to complete a song on expert difficulty.

You can win by either completing the song or cumming while still playing. You automatically get 5 stars for the song if you cum while the song is still on and manage to somehow finish the song.

"Hey, let's bang while playing Guitar Hero. Will call it the Guitar Hero Challenge."

getting the guitar 

Refers to making out or going into a makeout session
This saying originates from the many couples that go into a private room or a private area during a party or social gathering, have their makeout session, and when asked where they were, say they were busy "getting the guitar" So the 2 have been linked together into one phrase

James: Hey man, totally got the guitar with Jessica yesterday!
Friend: sweet!

Tyrel: I hooked up with this new girl, am totally getting the guitar with her on the first date!
Friend: damn you move fast !

Billy: I really like this girl I think she's the one
Friend: Don't act too thirsty, or she won't give you the guitar!
