Colonial mindset
A deep routed inferiority complex that people of an ethnic group or country, usually with a colonised history (India, Philippines, Carribbean, African countries) have towards white people (usually British).
Alatunde has a colonial mindset. When he's at work he puts on a fake posh accent to impress his white employer. He was talking about marrying a white blonde girl as a symbol of wealth and status but deep down isn't confident enough to approach a random girl.
