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.

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.
