A person or persons who deliberately partake in cultural assimilation via musical selection, cultural fads, fashion, or activities to garner a sense of high self-esteem and avoid rejection by one's peers even if it means sacrificing morality, taste, or common sense.
Society is comprised of a large number of pop culture groupies who listen to music and watch movies that are mediocre because it is poplar amongst their peers. Men are even starting to blur gender boundaries by wearing pink because they see celebrities do it on television.
Girls who always hang out at bars/clubs in Koreatown (k-town) because they're obsessed with Korean dudes (mainly non-Korean Asians in love with k-pop). They hang out at the same asian bars/clubs and hook up with Korean bartenders or promoters and their friends. K-town groupies can easily be spotted as they always get free shots from the Korean bartenders.
Friend A: Check out those hot asian girls over at the bar.
Friend B: The Chinese girls? They're k-town groupies. They're here every weekend to drink and hook up with the Korean bartenders. It's all that k-pop craze.
Friend A: How do you know that?
Friend B: My friend told me. He's a bartender here. He knows the deal. Give those K-town groupies free shots and he'll get lucky.
A person who always responds to another specific person's (i.e., the "target person") facebook status updates and links, typically within the first few minutes of it being shared.
The facebook groupie either 1) intensely romantically likes the target person, 2) wants to BE like the the target person, or 3) wants to be accepted by the target person's group of friends. The facebook groupie is often among the very first to respond to the target person's status updates/links and very rarely let's a target person's status update/links slip get by without a response.
They are often unaware how embarrassing, lap doggish, or futile their behavior appears to be. While the facebook groupie is typically of the opposite sex of the target person, facebook groupies can be the same gender as the target person.
Caveat: The term facebook groupie does not extend to family members or significant others. Therefore, you cannot be a facebook groupie to your husband/wife boyfriend/girlfriend, sister, brother, cousin, etc.
