I was a participant at an exorcism when I was 16. There were about eight youth and a youth leader present. It was on a Wednesday night after a youth Bible study. It took place in front of the altar at my church.
The girl being exorcized was just out of high school. I don't remember why we thought she was possessed. I never saw her act weird. Maybe she was depressed.
She laid on her back on the carpeted floor at the front of the church. Her eyes were closed. The guy in charge had a small cross and sometimes placed it on her chest and forehead. We all knelt around her and told the demon to leave. We sang praises to God. There weren't any violent motions. No puking. Her eyes didn't roll back in her head. The highlight of the evening was when the leader asked the demon his name. The demon said, "Fuck you. This is my cunt!" That was cool and just a little scary.
The girl's belly was showing and her nipples stuck through her shirt. Maybe she was cold, or horny. We kept singing and praying. The leader kept pulling the girl's shirt down to cover her belly. I noticed a boy across from me staring at her erect nipples. She laid there for about 30 minutes. After awhile I guess we all got bored and ended it. Kinda anticlimactic.
You'd never know the girl had a demon. She looked and acted the same after the exorcism as she did before. Five years later, her cunt still belongs to Satan.
