"Throw Back Bitch" is a porn video tag that combines two elements: the phrase "throw back" and the term "bitch."
"Throw back" is often used in slang to refer to something from the past or nostalgic. It could mean the performers are reminiscent of a previous time, era, or trend within the adult industry. Alternatively, it could also be referring to a scene or content that is intended to evoke nostalgia in the viewers due to its similarity with past works or styles.
"Bitch," on the other hand, can be used as a term of endearment or dominance within certain sexual contexts. In this case, it likely emphasizes the performer's boldness, confidence, and dominant demeanor, possibly even playing into a specific fetish or fantasy related to dominatrix-style content.
Overall, the tag "Throw Back Bitch" could imply that the video features performers who evoke a nostalgic feeling or reminiscence of past styles or trends in adult entertainment, while also incorporating elements of dominance and female empowerment.
