Ragging

Ragging is a practice similar to hazing in educational institutions. The word is mainly used in India, Pakistan, Bangladesh and Sri Lanka. Ragging involves existing students baiting or bullying new students. It often takes a malignant form wherein the newcomers may be subjected to psychological or physical torture. In 2009 the University Grants Commission of India imposed regulations upon Indian universities to help curb ragging, and launched a toll-free 'anti ragging helpline'.
