The act of a female performing felatio, whilst in the middle of sexual intercourse, whilst at the same time performing a "wristy" and at the same time tickling the male involved. The origins of this word came from the ancient Greek hero Hercules, who would often perform this sexual conduct in an open field, and when he climaxed he would often scream "CLOUD!" because they were the first things he saw.
