A fetish that acts as a mixture between emetophilia, oviposition, and vore, inspired by gastric brooding frogs (Rheobatrachus). Describes the process of swallowing fertile eggs, having them hatch in the body, and being regurgitated. Eggs are often that of worm-like creatures such as snakes, maggots, or centipedes, to enhance the focus on wriggling and squirming in the host's stomach.
Person A: Dude I just saw some fucked up hentai where a giant wasp laid eggs in a girl's stomach, and when they hatched she puked them up. Can't believe some people get off to this.
Person B: Oh yeah, that sounds like some Gastric Brood shit.
