The porn video tag "being-dik-game" seems to be a combination of English and possibly Dutch.
In this case, the English word is "be", while "dik" is an adjective in Dutch meaning 'thick' or 'fat', and "game" can mean either a type of board game or simply referring to the act of playing with something. Putting it all together, the tag "being-dik-game" could be interpreted as a play on words for a sexual activity involving a thick or fat body part being used in a game-like scenario.
However, without further context, the exact meaning of this specific porn video tag remains ambiguous.
