Say “like” to informally communicate someone’s words or thoughts:

She told me I was being unfair, like “You let everyone else do it but not me.” 

I was just sitting there, like “Am I the only one who thinks this is nuts?”

A more common version of this is with a subject and a be-verb. We use this more to talk about someone’s words:

I was like, “Can I get some extra napkins, please?”

I showed her pictures from the party and she was like, “Look at those girls and their short dresses!”
