I have gotten the Dictionary.com word of the day emails for years. Today’s is the best, by far.
vellicate VEL-i-keyt, verb:
1. To touch (a body part) lightly so as to excite the surface nerves and cause uneasiness, laughter, or spasmodic movements.
2. To irritate as if by a nip, pinch, or tear.
3. To move with spasmodic convulsions.
There are just SO MANY dirty jokes there.
