Thaipusam is a Hindu Festival that happens every January or February. Thaipusam is celebrated by the Tamil community in Sri Lanka, India, Singapore, and Mauritius. But nowhere celebrates it as big as Malaysia.
Celebrated during the full moon of the Tamil month of Thai, (January or February) Thaipusam draws thousands of devotees to pay their respects to Lord Murugan. It is a colorful and shocking Hindu festival where devotees pierce themselves with pins and spikes, hang pots and fruit off of their chests with hooks, and pull chariots or have people hanging onto a heavy rope attached to their backs by hooks.
