Big chop
Cutting off all relaxed or heat-damaged hair at once to start again with only natural hair.
Also: BC
The big chop is the moment someone moving from relaxed to natural hair cuts off all the chemically treated lengths, leaving only the new natural growth, which may be just a few centimetres. It is quicker than transitioning, which means growing the natural hair out over months while trimming the relaxed ends bit by bit. A very short afro after a big chop is often called a teeny weeny afro, or TWA. Many people film or share their big chop.
