Thanks everyone!
GAP Argentina has nothing to do with the clothes company.
It stands for Grupo de Amigos Playmobileros de Argentina, which in english would be something like, Group of friends Collectors of Playmobil.
"Playmobilero" is a spanish slang word for "Playmobil Fan" or "Playmobil collector"; or the person who likes playmobil .
Is there a word like that in English? "Playmobilers"?
