Hey wut does this phrase mean?

Question

he has a chip on his shoulder

Answer 1

Supposedly, a lumberjack who wanted to fight someone--anyone--on a Saturday night would put a wood chip on his shoulder and walk around town--or the tavern--with it.  So, if anyone inadvertantly knocked the chip off his shoulder, he would have something to accuse that person of, and get into an argument, and have his fight.  If you didn't want to fight, you'd stay away from someone showing that kind of belligerance.

Answer 2

he has anger problems

Answer 3

It means he has a grudge against someone or something.  

Presumably the chip is basically a weight, an irritant, a constant reminder that something is wrong.

Usually people who are said to have a chip on their shoulder seem angry all the time - either about something specific, or in general.

Answer 4

which simply means he's having a bad day, and everyone he meets he wants to fight,or argue,  with  if you run into anyone with a chip on his/her  shoulder, just say to that person:HAVE A GOOD DAY,AND GOD LOVES YOU! And then walk away; because he will lose the fight BECAUSE THERE WILL NOT BE ONE!
