Definition: When a man misinterprets a woman's sincere, non-sexual request for or offer of something as a sexual advance. In other words, he "hears" with his penis.
Example:
Female coworker: "Can we get together some time this week and go over the new brochures?" (Inner thoughts: "Sigh. I hope he doesn't think I'm coming on to him. I really hope he has his penis audio turned completely off this time.")
Male coworker: "Of course." (Inner thoughts: "She wants to fuck me." )
