The user might be referring to a video that's either about Tara's son being depicted as overdeveloped, which seems odd, or maybe it's a technical term. Since Tara Tainton isn't known for having a child in the public eye (she's an actress with three biological children and one adoption, as per her interviews), the "son" here might be fictional. Perhaps it's a character she played in a show or movie where her character has a son who's overdeveloped in some way. "Full UPD video free" – "UPD" might stand for "Update," but in the context, maybe it's a typo for "UPD" as a website or service offering the video for free.
