When you perform some act that turns a previously-told lie into a truth.
A lies to B about going skiing in order to avoid going to a boring event. Later, A decides skiing sounds like a great idea after all, and does it, hence unlying about skiing.

Get the unlie mug.
An ancient Norse word literally translating as "By the grayest hairs of Odin's mighty beard it shall not come be."

If I was wrong I would be unliely to admit it.
