S.W.A.G.

S.W.A.G. (or Swag, or Swagger) originally referred to the 4 important skills for a fairy's success: As of this post, it's undecided as to whether these skills level up via training, or have predetermined specialties based on which character model is chosen by the player.
 * Sass - negotiation & charm, and performance under pressure. Also, how much of a boost you get when Power Stripping.
 * Waggle - how to read reactions and adapt one's seduction techniques (ie: bonuses before equipment and buffs, newphy's resistances passively reduced).
 * Assets - How well a fairy can carry a style (ie: bonuses from equipped items). Allows fairies to make more use of their favourites, even if they may be weaker than others.
 * Glamour - The strength of a fairy's aura, which passively brings newphys under the fairy's charms, and may even cause them to swoon instantly. The radius of effect and chance of instant-swoon increases as this levels-up.
