Mark is a cretin
The lowest form of humanity. A person that is a waste of air. A person who is lazy and dosent contribute anything to society.

A weak or trifling ass person; labeled as a "mark" indicating they're vulnerable to getting rocked. Just an all-around trick.

An advertising monopolist who exploits people's personal information to sell targeted advertising on the internet.

The Mark Effect (n.)
The psychological phenomenon in which an individual with little to no offline grounding begins to place disproportionate importance on online achievements, perceiving them as markers of superiority. Over time, this distorted valuation erodes their sense of reality, leading to an inability to distinguish between their digital persona and their real-life self.
