Guile
Guile is a General Ability that represents various forms of deception: the ability to lie, certainly, but also the ability to disguise one's self, bluff, or feign emotion.
Guile is usually used in an Opposed Roll, with the intended target of the deception rolling Perception + Folk Ken (or some other Ability, if the Storyguide feels another Ability is more appropriate for the situation).

Commentary
If a player rolls a zero on a Guile Stress Die, the Storyguide may want to roll the botch dice in secret, so the player won't immediately know whether he botched or not. That way, there is room for doubt whether the intended target fell for the deception anyway, or saw through it and concealed his response.
