GRO
A girl working in a club or bar in the Philippines to keep male customers company. The "Guest Relations Officer" or GRO always gets the men to buy her inflated priced "Ladies Drinks" that she gets a monetary kickback from. Nearly all GROs are prostitutes who can be "Bar Fined" and taken from the bar for short time or long time sex. Nearly all GROs fall under the auspices of the "Maddam" and live at the bar or in substandard dormitories provided by the bar.
After the cute little GRO got me to buy her several ladies drinks, she suggested I bar fine her and take her back to my room for all night sex.
