oga
Used by Nigerian scammers, this is similar to the Ghanaian "chaley", meaning the same as "dude". However in this context it usually means a scammer higher up the chain, who controls other scammers - like a lame version of a Mafia Don.
The scammer's oga wrote to the victim, pretending to be the "barrister"
