As we all know, the female breast gives out large quantities of tractor beams drawing a guy's eyes to the prize. Melon gazing is the act of staring with a stupid expression straight at a woman's chest until she slaps you or leaves.
Woman: Is there a less harsh way you could melon gaze?
Man: What? Oh, yeah, car insurance and stuff.
*continues to gaze*
Woman: OMG! The male race are pigs!
*slaps man and becomes lesbian*
