in the rattle

English edit

(UK, naval, slang) Kept in confinement as a disciplinary measure.
- 2005, Charles Gidley Wheeler, Jannaway's Mutiny:
  If you were in the rattle too often, you would be labeled a troublemaker. Once that happened, it was virtually impossible to get back into the Navy's good books, and the chances were high that they would find some way to get rid of you.
