Wife acceptance factor
Wife acceptance factor, wife approval factor, or wife appeal factor (WAF) is an assessment of design elements that either increase or diminish the likelihood a wife will approve the purchase of expensive consumer electronics products such as high fidelity loudspeakers and home theater systems. WAF is a tongue-in-cheek play on electronics jargon such as "form factor" and "power factor" and derives from the stereotype that men are predisposed to appreciate gadgetry and performance criteria whereas women must be wooed by visual and aesthetic factors.
