Dude, is that guy drunk or is he just guitarded?

1: guitarded as in person with retardation playing guitar:" Hey Mikey, Did you know that Billy with the downs is learning the guitar?"
" Ah...so he's guitarded now, right Jeffrey?"

2: Guitarded as in a person that lacks musical knowledge.
"Dude. You don't even know what a Fsharp/D chord is!? And you've been playing for three years? No offence, Mikey, but you're guitarded."

3: Guitarded as in "person that is poor at playing the guitar": " Says Mr. Jeffrey who's so guitarded that he can't even play the G chord!"

4: Guitarded as in a reference to the music store chain Guitar Center: "Mike, I'm sorry." "I'm sorry too, Jeff. How about we go kill some time at Guitarded center?"

Joe: "Oh wow, I could never play one of those! Too many colors to press at once!"
Jim: "You are Guitarded."
