Wiki of "Ah Lian & Ah Beng"

"Ah lian is a pejorative term commonly given to a certain group of young Chinese girls in Southeast Asia, especially Singapore and Malaysia. These chinese girls, whose age ranging from their adolescent years to late 20s, usually centralised in the busier and more developed cities in the region. They are regarded as bimbos, and are stereotyped as anti-intellectual, superficial, materialistic, and shallow.

The Ah lian "culture" is especially prevalant in schools, typified by their frequent use of vulgarities and appearance in cliques(joined by their male counter parts Ah bengs).

Ah Lians commonly speak in a kind of hybrid mix of Singlish and Chinese, or Chinese-related dialects. It is also common for the grammar from these dialects to cross over English usage, creating English phrases with Chinese grammar."

Ah Beng is a term commonly given to a group of young Chinese men in Southeast Asia, particularly Singapore and Malaysia. These Chinese men, whose age ranging from their early teens to late 20s, usually centralise in the busier and more developed cities in the region. Ah bengs typically speak local slang, which is Hokkien or Cantonese mixed with English and Malay, such as Manglish or Singlish. They are often stereotypically portrayed to be anti-intellectual, superficial and materialistic and shallow. These values often lead to a lack of culture or indulgence in criminal activity or being involved in brawling or affray out of disagreement with other people.

Ah Beng comes from the romanization of the Hokkien pronunciation of 阿明. 明 is a word commonly used in the names of Chineses in the region; it means bright.
