Johnny Deeper means in slang: Johnny Deeper, a fictional boy of the ages, appears in several sexually explicit stories referred to “Johnny Deeper Jokes”. These stories are shared among elementary-aged males and can be their first introduction to sexually-themed humor. The stories revolve around Johnny Deeper, a character who is **** with teachers and vulgar in class. This is why the series has remained popular with this age group. While some jokes only play off Johnny’s name, others are far more complicated and portray Johnny as an innocent, yet loving, elementary school student. (in Slang Dictionary, added by Keely Decker)
