A creature from the sea that makes its way to happy beach goers privates and attacks them with their snippy things. Snip snip. Snippity snip. Can be passed on through sex and the use of pubics. Hightly visible through clothes and other items to hide your bits due to their vast size. An STI with a purpose :)

Disgusting pubic infestation after shagging something who already has it, or in a very rare case, having your first ham-shank.(Like my pal Allan B)

Makes you walk like John Wayne with a poker up his arse

A nickname for a woman who has pubic lice or has had the condition a number of times. Often wears the little critters as a badge of honor and adopts little pet names for each individual crab.
Crabs works at Costco, but beware she didn't get that nickname from selling seafood.
