An act and exchange of verbiage between two consenting adults.
The Cowardly Lion (verb) is an act described as follows: While doing your girl from behind, at the point of her climax she has to scream "hippopotamus" and just before you blow your baby batter all over her back, you scream "I'll cock you from top to bottomnus"
When you shave your pubes with an electric trimmer but don't get the hair on your shaft or balls cause it nips you. So the finished product resembles the mane of The Cowardly Lion.
I was manscaping but didn't have my Mach 3 nearby. So I half assed it and the result was The Cowardly Lion.
