In the 1990s, in Birmingham, UK, when some children played outside in areas with very few people, and who became temporarily split up and lost from their friends or family while playing, they would shout “Oggy, oggy, oggy” for their friends or family to hear their general direction and to respond with “Oi, oi, oi”. They used this to try and find each other again through sound and hearing. This may not have been limited to the 1990s, and may not have been limited to Birmingham, UK.
