The habits listed below are unspeakable and sometimes embrassing, which if not caution can be ....
1. Rubbing one's armpit with the hand, and next to the nose. For what? Smelling i guess!
2. Scratching one's buttock in the public
3. farting in the public. Bearing this slogan in mind ' ko si ile fun iso'(no house for fart).
4. Picking up a grain of rice, that fell, then straight to d mouth.
5. Only 10% of nigerians brush at night.
And many more you can add yours.
