The term "cjxxx" appears to be a non-English abbreviation, and may not have an exact translation. However, in the context of porn video tags, it is likely used as a shortened form for describing a specific type of gay porn content. This tag could represent a particular category or theme within this genre. Due to its ambiguity, it might be useful to provide additional information or more context to better understand its meaning.
The "gay" in the parenthesis simply indicates that the content involves male-on-male sexual activity.
Please provide more context or clarify the abbreviation for a more accurate explanation.
