Poser

Poser is a pejorative slang word used to describe trend seeking individuals who are into something due to its popularity rather than anything enlightening or with actual enthusiasm and interest.

With the term Hipster, both names can be comparable to the terms of Newfag (Poser) and Oldfag (Hipster). Posers are generally disliked due to their detrimental influence on the legitimacy and content of whatever thing they are into, often due to their shallow nature and consumerist mindset in mass numbers capable of diluting down the original spirit and reasons why something was good in the first place.
