What does "oneitis" mean in slang?
The term "oneitis" is a modern slang word formed by combining "one" with the suffix "-itis," which is often used in medicine to describe a condition or obsession. This construction humorously suggests being "affected" by one person. In online and dating-related communities, it refers to an intense fixation on a single romantic interest, often to the point of ignoring other possibilities. It usually carries a slightly negative tone, implying unhealthy attachment or lack of perspective.
Examples
He's got oneitis for that girl from work and wo n't even talk to anyone else.
