👉 The term "pizza infection" is a metaphorical and somewhat humorous way to describe a situation where a food, specifically pizza, is perceived as carrying an invisible, harmful agent—often humorously referred to as "pizza virus" or "pizza contagion." This metaphor suggests that just as a physical infection spreads between people through contact or bodily fluids, a negative perception or "infection" can spread rapidly through social media, cultural trends, or personal experiences. For instance, a viral video of a pizza being eaten by someone with a questionable health status might lead to widespread concern about the safety of pizza, even if scientifically unfounded. This concept highlights how easily perceptions can become contagious, influencing public opinion and behavior without any direct biological link.
