Naiguma
You become a naiguma when you go to Nigeria and start saying nonsense words like 'wetin' and think you're smart because of it.
I became a naiguma after I said 'wetin' to my boss and he asked me to repeat it three times.
My brother turned into a naiguma when he tried to impress his crush with Pigeon.
I got called a naiguma for saying 'eniya' like I knew what it meant.
