trick bag
n.— «Because there are so many confidential informants and sex offenders, the Bureau of Prisons (BOP) does not allow Pre-Sentence Reports to be in a convict’s possession. Inmates throughout the BOP suffer boot-parties on an alarming scale because of this “trick bag.”…Borrowing or loaning personal items leaves one open to becoming a victim. It’s called a “Trick Bag.” You never know what might develop. » —“Cell Survivor” by John Bowers Salt Lake City Weekly (Utah) Apr. 28, 2005. (source: Double-Tongued Dictionary)
