The Finger Warmth Stealth Attack is one of ingenious cunning and skill. In layman's terms, a single finger of the unsuspecting victim is inserted into ones own anus without them noticing. The result upon realisation is not one of disgust, but of pure awe and respect for the immense skill and aptitude required to pull off such an attack...
