Often favored by teens - Mall rats easily spring to mind - & young adults wanting to project belonging to a group, culture or common state of mind, herdware can include the ubiquitous naval, ear, nose, lips, genital, etc., body piercings. Or out-of-the-box tattoos like Celtic, faux-tribal, barbwire, ad nauseam designs.
Types or styles of clothing, jewellery, cellphones, and any other hackneyed device, appliance or conveyance can devolve into herdware.
Example: The group gathered every Saturday evening and flaunted their herdware at one another and imaginary admirers.
Example: With her herdware of fresh tatts and piercings and dangling iPod she felt she was the coolest teen in the mall.
