Nigerian lady has given an unexpected reaction to a public proposal by her boyfriend at their school.

A video which has gone viral on social media shows the moment a lady slapped the man who proposed to her in public.

The incident reportedly happened at Ambrose Ali University Ekpoma in Edo state.

The young man could be seen kneeling down with a ring in his finger, asking the girl to marry him.

But she appeared irritated and was obviously in objection of the proposal even though onlookers cheered and urged her to say yes.

The lady was venting and pacing up to the point her boyfriend said he loves her and she responded with a slap on his face.
