Crabs

A slang term for “pubic lice.”

An STD that is caused by a parasite. Pubic lice live in pubic hair and lay their eggs. They can cause intense itching, especially at night. Public lice can be sexually transmitted but can also be transmitted if people share towels or other linens. They are cured with anti-lice medicated shampoo and body wash, such as Kwell, which can be purchased in a drug store.
