I think you need to shift the idea from poultry to physics. This isn't necessarily a chicken and egg scenario as it is about metal and magnetism (douchiness).
Metal doesn't necessarily start out as magnetic, but when pointed North and struck with another piece of metal, it can become that way. This is really how it probably began, two non-magnetized materials found themselves in a position where they became magnetized. Then this magnetic bond can attract magnetized and non-magnetized materials alike. The pre-magnetized materials form a deeper bond to their magnetized roots, while the non-magnetized are picked up and turned into the magnetized. Some materials like platinum just can't be magnetized and find themselves able to reject any bonds to the magnetized agalmation up North.
So, we take that theory and we come to the idea that some well meaning pioneers took a backwater town and attempted to turn it into a "center of learning" for the Old Southwest in the 1830's. This is fair play. Outside of the laughability of a "center of learning" that didn't know how to pronounce "Lafayette", who wouldn't want that kind of boost to the local economy? Somewhere along the way, they got the douchey idea to name it "Oxford" with the intention of tricking the legislature into putting the state's first university there. This is the point where we see the materials become magnetized. This douche magnet attracted other douches and those that were douche-adjacent ("pre med", "pre law", family members of existing douches, locals, Texas kids that couldn't get in to SMU/Texas/Texas A&M/Texas Tech/Baylor/TCU/Texas State, etc.), effectively turning the douche-adjacent into douche-proper. Some folks are able to (in many cases very easily) resist or outright reject the douche magnet and those people are lucky enough to call themselve Mississippi State fans.
