i mean i know you're taking the piss, but Dan O'Bannon has talked at length about how he did very much deliberately write the movie to attack a male character in a way that invoked oral rape and violent childbirth because he wanted the film to create sexual anxiety and fear in the men in the audience, which he felt was an untapped potential in horror

"Dan O'Bannon specifically wrote this scene with the male's fear of penetration in mind and wanted the scene to operate as a payback of sorts for all of the times horror films have subjected weak women to male predatory monsters. His goal was to reverse the stigma associated with the sexualized violence against women in horror and turn the idea back on itself. It's no coincidence that the chestburster's birth involves a forceful invasion of male bodied victims and concludes with a phallic entity being born out of a male's chest."
