The last ones. Sorry for flooding the thread with my posts.
'Ordinary' can also be used (in Nig.) interchangeably with common or local, depending on intention.
Eg: "So you won't share ordinary/common (not a big deal/can be gotten easily) peanuts with me?'
(On its own) 'I'm just wearing ordinary (normal/casual or simple and nothing fancy) clothes'.
(When used negatively) 'You're just an ordinary/common/local gateman' (low class, poor, of little value).
Mammy is short for 'Mammy-water'/'Mami-wata' in Nigeria (Water Spirit or water goddess or sea goddess or water demon).
Yes I didn't realise Oriental was racist too although I've only ever heard it used to describe things in Nigeria, not people. Oriental rug, oriental vase, etc.
