The porn video tag "dlisgame" seems to be a combination of two words: "dli" and "isgame." The term "dli" could potentially stand for "double penetration" or "double-sided," while "isgame" appears to refer to a "gaping" sexual act. So, combining these two terms, the tag might be interpreted as meaning a video involving double-sided penetration with gaping. However, this interpretation is only an educated guess, as the exact meaning of the tag may vary depending on context or language used.
