Someone who is a piece of crap. A boogie (or booger), comes out of your nose. Crap comes out your ass. So it's basically saying that you're a piece of crap if you're an assboogie.
Don't listen to them, they're all assboogies anyway!
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.
