The porn video tag "loly" seems to be a typo or misspelling. It might be a combination of two words: "lolly" and "loyal".
1. "Lolly": In this context, it could refer to oral sex, as the term "lolly" is sometimes used as slang for fellatio (oral sex performed on a man). This interpretation would make sense in the context of a porn video tag.
2. "Loyal": This word typically means faithful or constant in affection or purpose. In the context of a porn video tag, it could suggest that one partner is being loyal to the other during their sexual activity or relationship.
Given these possible meanings, "loly" might be referring to a scene where a person is receiving oral sex (or "lolly") from someone they can trust and are loyal to.
