Yoruba Mothers, one of the best when it comes to child upbringing.

Yoruba mothers produce the best range of slaps: IGBATI, IFOTI, IGBAJU, IGBARUN, IFORUN, IFAKUN, ILADI, ABARA. These slaps will make you think you were adopted.
IGBATI will make u correct your wrong lesekese!
The beauty of IFOTI is, you will confess your
sins on the spot.
IGBARUN, IGBAJU and IFORUN will make you expose those who committed the crime with you without hesitation.
ABARA and ILADI will make you pee in your new pants! Now ABARA is the worst....
And apart from IGBAJU, we have a more advanced one which is IGBAJU OLOYI. When you receive that one, you'll lose balance and your head will go to auto-search as you'll be looking for what hit you. This will make you do all the actions of the other slapxs above at once!
OH! IGBAJU OLOYI...it can reset one to 3D (DEAF, DAFT and DUMB)
God bless our parents for the good upbringing!
