I can't multitask, I'm a unitasker
by jeffreygus February 16, 2010
An object with one function, ideally, designed to be extremely good at what it does. A waffle iron, for example, can only be used to make waffles, but it tends to make waffles extremely effectively, justifying its existence as a uni-tasker. Objects as varied as saddles to soap dishes or rice cookers can be considered uni-taskers.
The only uni-tasker allowed in your kitchen is a fire extinguisher.
