look up any word, like bukkake:
 
1.
Involves ejaculating on a girl's neck while titty-fucking. The pool of semen spills down the side of her neck, which creates the bowtie effect.
Her boobs were so big that not only did I titty-fuck her last night, but I gave her the ol' Chicago bowtie!

2.
When a female gives a hickey using her vagina on the neck of a male.
Sam what are you going to tell your wife when she sees the Chicago bow tie that the stripper left on you?

This is simply a phrase used to describe how a man's balls look while he's titty fucking a girl. Upside down, of course.
