The name Dixon is a boy's name of Scottish origin meaning "son of Dick". Dixon and is often added to lists like Film Noir Baby Names and discussed in our forums with posts like "Extended Family Congrats Round 2 (dice game)".
From the experts:
A relatively common surname, Dixon would be an inventive way to honor an ancestral Richard or Dick, the X form a lot livelier than the Dickson spelling, just as Dix is a more modern short form than Dick; it would be right at home alongside Dax and Jax.
But you don't need us to point out the considerable downside of this name. Besides being a sexual slang term, dick is also the most common epithet describing someone who's a jerk or a meanie (trying to avoid other unsavory words here). And Dix sounds exactly like dicks, which makes it not the least bit easier a name to carry these days than Dick.
