Have vs. of: (this one's a new one for me, but it's really, really, really bad...)
Right: "I should have raised there!"
Wrong: "I should of raised there!"

Hmm. So when would you say "should of" done something?

Um, never. It's never correct.

Also:

When you dominate someone, you are dominant, not 'dominate.'

It's ridiculous, not 'rediculous.'

When you lose weight, it makes your pants loose.

Is grammar (not 'grammer') important? Definitely (not 'definately').
