Marcheling
Marcheling is a term that emerged in the early 21st century, referring to the act of aggressively promoting oneself or one's ideas, often in a public or online space, with a sense of entitlement or perceived superiority. It is characterized by persistent self-promotion, a disregard for differing opinions, and a tendency to dominate conversations. Individuals who engage in marcheling may exhibit behaviors such as constantly posting about their achievements, interrupting others to steer the discussion back to themselves, and reacting defensively or dismissively to criticism.
The term is often used in a pejorative sense to describe individuals perceived as arrogant or attention-seeking.
