According to Urban Dictionary, an ABG is short for “aznbbybygirl” aka Asian Baby Girl:
Predominantly found in the cities and surrounding areas of San Jose, Los Angeles, and San Diego. ABG’s are the female counterparts to strong guys like us. They are the Yin (feminine) to our Yang (masculine). Though be warned – ABGs are known to have a WILD personality and showing any signs of weakness will turn them away. Every tough AZN guy, should find an ABG. On weekends, I usually roll up with my homies and entourage of ABGs to get KBBQ and hangout.
ABGs age well and stereotypically turn into the Housewives of SGV (San Gabriel Valley, California).
Below are examples of what ABGs look like, but remember, it’s not just the looks – it the attitude/lifestyle that makes an ABG.
