"Stokings" seems to be a misspelling or a typo. The correct term might be "stockings." Stockings, in the context of porn video tags, generally refers to the fetish of wearing or being attracted to women wearing thigh-high, opaque or sheer stockings. This can include pantyhose, tights, and other similar leg wear. In a pornographic setting, this might involve scenes where actresses are wearing stockings, or scenarios that specifically focus on the removal or display of these garments.
