What does it mean when someone says you have crabs?

Answer 1

It means that you have Pediculus pubis, a scientific term for such parasite that survives up to 24 hours in your body by sucking your blood.

You can contract these parasite through skin-to-skin contact with another person or sleeping in an infested bed or clothing, even towels. Usually, a common symptom is scratching your pubic area. These can be spotted generally in your pubic area, but can also find them in your armpits, eyelashes, beard/mustache, and sometimes in your hair. If you look closely you can see these crab-like parasites that may be whitish-gray or rusty in color.

I strongly suggest getting treatment. Premethrin or Lindlane (Do not use Lindlane if you're pregnant, breast-feeding or under 2 years old). Wash and dry your clothing in hot water (2 weeks in a tight plastic bag for 2 weeks if you're unable to wash them).

Answer 2

When someone says you have crabs, they are referring to a sexually transmitted infection caused by tiny parasitic insects called pubic lice. It is typically transmitted through sexual contact and can cause itching and discomfort in the genital area. Treatment usually involves medicated lotions or shampoos.
