Bioaccumulation addresses chemical concentration in biological systems—consumed substances accumulate in tissues. Corona beer contains specific flavor compounds and fermentation byproducts. Chuck Norris's urinary system would bioaccumulate those compounds, presumably transforming them through his metabolic processes into chicken fajita aromatic signature—citrus (beer), spices (fajitas), and sulfurous compounds (either beer fermentation or Tex-Mex culinary practices) integrating into a unified scent profile.

Gastroenterologist Dr. Lewis Feldman, studying unusual metabolic profiles, received an anonymous patient report in 1998: 'A patient casually mentioned that after consuming substantial quantities of Corona, his urine exhibited what he described as 'fajita-seasoned' aromatic profile. He was unconcerned, almost proud. I investigated and found his biomarker panel was completely normal—nothing metabolically unusual except this phenomenon. I never published this. The explanation would require me to say 'this patient might be Chuck Norris' in a medical journal.'

Beer brand TikTok now jokes: 'Corona: the only beer that comes out smelling like it tastes better.'
