Diversion testicles are a set of rubber testicles that you hold up in the air and shake like a bell. The purpose of diversion testicles are to distract your co-workers from eating a meat and cheese platter, so you can surreptitiously sneak under the radar and eat the platter yourself.
Dale held up some diversion testicles during a staff meeting to distract his coworkers from the snack platter that was in front of them. Dale then ate the snack platter while his coworkers were distracted.
