It can't really be defined. Nojob is a word you can use for alot of stuff. Like people and deeds. In theory it means that someone who is a nojob won't get a job, or at least only get a bad one. Like a construction worker who used to smoke crack and didn't pay attention in school.
Example 1
Guy1: Look, that guy is smoking weed in class!
Guy2: Hahhaha, what a Nojob!
Example 2
Guy1 and Guy2 talks to another random guy at the start of a new school year. The random guy tells them that he used all his savings on cigarettes and that he got an F in some of the classes last school year. Guy1 and Guy2 walks away and Guy1 whispers "WTF! That's super nojob hahaha!"
A guitarnoob is usually quite a young guitarist who thinks they can do lodes of fast shred soloing just by randomly picking and sweeping notes. They are usually found in guitar shops and guitar exhibitions like music live or NAMM playing the best guitar on the loudest amp deliberately in front of other people trying to show off a false sense of musical knowledge and technicality when they sound absolutely terrible, there for making a complete noob out of them self.
Typically, guitar noobs practice alot but are too arrogent to take criticism so just keep practicing all the wrong things there for staying at the same level of playing for a very long time.
Randon guitar shop guy: Hey, you ever heard of Yngwie Malmsteen or Steve vai, shit, man those guys can shred on guitar!
Guitar noob:Ah yeh, those guys are kwl but some of there stuff is actually quite easy!
Random guitar shop guy: No way man! lets hear u do some of their stuff!

Random guitar shop guy:Yeh.....kwl....(walks away).....What a freaking guitar noob....
