The Holotypic Occlupanid Research Group (or HORG, ) is a parody research organisation which studies bread clips (called "occlupanids" by HORG) as if they were living organisms with a focus on synthetic taxonomy. Plastic bread clips may perforate or obstruct the gastrointestinal tract, and are potentially fatal. This prompted the site creator to treat the cataloguing and study of bread clips as important, as if the precise identification of bread clips could save lives.
The parody site has been noted by independent media, drawing similarities to real taxonomies, and noting how the synthetic taxonomy can assist in learning the design history of the object itself (bread clips).
HORG's efforts were included in a 2018 exhibition comprising Mmuseumm's sixth season. "Milk & Bread", a 2025 art and design work by Susan Goldberg, mentions HORG. It was inspired by her experience collecting and displaying bread clips before and during the COVID-19 pandemic and how their display can reflect the increased workload and repetitive domesticity put on women and especially mothers during lockdown.
Terms coined by HORG have found their way into academic research.
