It was African slang and I was from there

 In another life when I lived in Russia, my husband once said about a friend that he was kind in love but not much that the went to bed with his wife, one moment he said that even he or the husband was the first, I asked who was the lalau, who was the robber, who was the person that was incognito, who was the 3rd the person that nobody knows?
