Not exactly a 'term' of abuse - just abuse applied with skill.
When I was an apprentice one of my mentors was a man just coming up to retirement, Jack Warrington.
He did his level best to make me a good tradesman, but at the time I was more interested in music than I was of being an electrician.
One day when I was proving particularly obtuse he turned to me and said thoughtfully, "You know, when you were born I think they must have thrown the wrong bit away"!
Treasured it always and used it often.
