Obialo
Obialo means someone who will make you laugh, but will also scream at you for no reason. They’re shy, but they’ll tell you they like you in front of the whole school.
My obialo friend laughed so hard, he fell out of his chair.
She stayed quiet all day, but then stood up in front of everyone and said, 'I like you.'
He screamed at me for eating his favorite snack.
