Wrong writing and saying of 'should have'
Many people mishear 'should've' and hear 'should of' instead. Same procedure with 'must've' and 'could've'
I should of learnt some better English.

What idiots say instead of should have. It makes most people want to stab the offender to death.
"I should have not said "should of", becuase after I did I got a screwdriver to the face."

Ignorant way of saying, texting, or posting on facebook the contraction of should have (should've). Especially pathetic when supposedly educated people use the phrase.
I should of paid attention in high school English class so my participles wouldn't be dangling.

When you say someone has the ability to do something, and it would be advantageous to do so; they should.

However, it usually means "you better fucking ... bitch!" just in kid-friendly tone.
Jane: You should stop drinking.
Bob: You better fucking make my dinner bitch!
