Soi-Boy

Used by the younger ex-pat community in Thailand to describe someone who spends entirely too much time in bars or go-go clubs.

Plays a pun on the fact that side streets in Thailand, commonly home to various forms of brothels and bars are known as "soi-number".

Guy 1: "He became a total soi-boy. Got a divorce, moved to Thailand and moved in at a ladyboy go-go bar."
