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.
Mike loved unitasking despite never meeting his targets because of it. Each time someone talked to him he had to switch off his computer in case he would multitask by accident.
It's a mixture between a Potato and a Unicorn, some people call it a "Unitato" but instead of potato, it is potater, and you can call people that who are so awesome!
People that go to university and possibly have a love for indie music like the Stone Roses or The Courteeners. The Uniwanker is not complete without one or more piece of Stone Island merchandise & in in-depth knowledge of their local football team. Uniwankers also have a tendency to repeatedly call other students Uniwankers as they cannot come to terms with themselves being one. The greater spotted uniwanker will consider themselves to have top banter, when actually it's shite. Lastly, general pains in the backside.
