I've had it (up to here) (with someone or something)
I'm frustrated to the point of exasperation (with someone or something). In this usage, the phrase can be followed with "up to here" as an intensifier. I called a babysitter because I've had it with toddler temper tantrums today. I've had it up to here with the lack of raises at this job. Why do I even bother putting forth effort every day?
I've had it up to here (with someone or something).
I will not endure any more of someone or something. Bill: I've had it up to here with your stupidity. Bob: Who's calling who stupid? John: I've had it up to here with Tom. Mary: Are you going to fire him? John: Yes.
