In this case, seems to be making a humorous comment about physical characteristics, specifically regarding gluteal proportions in individuals of African descent.

Historically, these physical traits were exploited in the 19th century, most famously in the case of Sarah Baartman

In the 19th century, European "scientists" and showmen used physical traits like steatopygia to categorize African bodies as "unusual" or "exotic." By labeling these proportions as anomalies or awarding them a pseudo-scientific "number" in catalogs of human curiosities, colonial powers sought to dehumanize African women. This was part of a broader effort to establish a racial hierarchy, where any deviation from European aesthetic norms was treated as a medical or evolutionary "extreme." Steatopygia and Biology

The specific focus on "extreme gluteal proportions" refers anatomically to steatopygia—a genetic characteristic involving high levels of fat accumulation around the buttocks and thighs. This trait is historically prevalent in specific indigenous populations of Southern Africa, most notably the Khoisan people. Rather than viewing this as a normal variations in human genetics, colonial scientists treated it as a spectacle, cataloging it under bizarre awards, exhibits, or "scientific breakthroughs" in racial categorization. The Case of Saartjie Baartman

Audiences paid to view her body, which was marketed as an exotic anomaly. The exhibition combined voyeurism with a false narrative of scientific education.
