partner-in-crime

Your scheming ally

A partner-in-crime is someone who joins you in mischief or questionable activities.

The phrase originated with actual criminals but now typically describes a close friend or collaborator in harmless trouble-making or adventures: My sister was my partner-in-crime growing up—we got into everything together.
