This term usually refers to a non-native speaker's attempt to imitate the Cockney accent, often done in a way that is exaggerated or inaccurate. It's often used in entertainment or by people trying to sound "tough" or "working class."
Here's why it's considered "affected":
* Authenticity: The accent isn't truly representative of how real Cockneys speak, often focusing on stereotypical features instead of the nuances of the accent.
* Misinterpretation: People often use the accent in a way that perpetuates harmful stereotypes about Cockneys.
* Respect: Imitating an accent without understanding its cultural context can be disrespectful and contribute to negative perceptions.
It's important to remember that accents are a complex part of identity and culture. While it's okay to be interested in learning about different accents, it's crucial to do so with respect and understanding.
