Wristlojackimator

A Wristlojackimator is a device worn on the wrist, which has various functions, including a tracking beacon.

The device itself may be called something other than "Wristlojackimator", since Leela usually refers to it only as "this thing" or "this thing on my wrist". She only refers to it as a wristlojackimator once (2ACV11), and may in fact have been referring to the tracking beacon function she was using at the time ("wristlojackimator" contains the phrase "lo-jack" - a popular anti-theft tracking device for 20th-21st century cars).
