IJGB is Nigerian slang. It stands for "I Just Got Back", and signifies wealthy Nigerians who show off their riches. It is said, such people start every sentence with "I just got back from London" or "I just got back from New York", hence they're called IJGBs.
This design was inspired by Nigerian Ankara prints which are popular throughout West Africa.
