what does "hp" occur to be about?

HP is also a kind of brown salty-umami sauce that people use like soy sauce or ketchup.

I would use it either for Hewlett Packard or for HP sauce, named for the Houses of Parliament.

Horse power, home page, Hyde park, hydrogen peroxide, America West Airlines (airline code), health plan & many more (check out the source below).

Hewlett Packard - software/computer products.

in many spanish speaking countries HP is the same as SOB

HP=hijo de la puta (Son of a whore)

hater pride
