Rdlh

Rdlh: verb. To make someone guess a word by removing all the vowels and one consonant and adding a random consonant to the end. As you've hopefully figured out this word comes from the word 'riddle' and is actually an example of itself. This 'game' was created by Benjamin Franklin when he had five spare minutes, while waiting for a plane...I mean ship. Other examples of this include "ncdf" and "rmvgs".
