It's mathematics slang for cutie pie. Seeing as 3.14 is the value of pi, well actually 3.141593 is probably closer even though it's an infinite number so 3.14 will do, but yeah you can catch my drift.
Usually in a text message or written/typed message of some sort:
Guy 1: Did you see andrea?
Guy 2: Yeahhh! She's a QT 3.14
Guy 3: lol i see what you mean. lol.
church hurt is where you experience a degree of distance, pain, or judgement from your church community. Essentially, you are just unable to “find your place”. This is prevalent in the Christian community, but can be extended to other religions.
Now that I am an adult I am beginning to heal from the church hurt that was inflicted on me as a child.
