Hank Spank

A very unexpected or aggressive advance or act by a person who is usually very quiet, respectful, and reserved. A person who is normally quiet and mild-mannered in everyday life who, when put in an intimate setting, becomes uncharacteristically charming, bold, and aggressive. Where he normally would have stopped at kissing, may suddenly convert to his "other self" where the unsuspecting girl/victim finds herself bent over a chair or couch while he attempts to give her the "Hank spank." The word Hank refers to the character in the film "Me, Myself, and Irene," played by Jim Carey. In the movie, his character develops an uninhibited split personality known as Hank.
