"Enormous Cock" is a common porn video tag that refers to a male actor in the video having an exceptionally large penis. This tag is generally used by viewers who are interested in or have a preference for scenes featuring larger-than-average penises, often referred to as "big dicks." The term "enormous" implies that the size of the penis in question is particularly noteworthy and may be considered above average. This tag can help viewers find content that specifically showcases such scenes, catering to their specific preferences or fetishes.
