Fish and chips ... Crumpets ... Russell Brand ... hating the Irish -- these are things British people LOVE. Oral sex, however, does not belong on that list ... so says authentic British person Lisa Vanderpump.

In related news ... Lisa shot back at a report someone ate box at her restaurant -- cardboard box that is.

LV says the allegation that a patron found cardboard in a Villa Blanca salad is ridiculous ... but says even if it were true, the patron should be GRATEFUL ... 'cause cardboard is high in fiber.

Love her.
