A doctor has let TikTokers in on an unconventional hack to gauge the size of a man’s cock without him dropping his trousers—simply by glancing at his hands. A TikTok clip of the member-measuring shortcut has topped 915,000 views on the video platform. “You can guess the size of a man’s cactus by how short his index finger is,” Dr. Karan Rajan — who goes by @dr.karanr on TikTok — said in the 27-second sexplainer.
The doctor cited a 2011 urological study in the Asian Journal of Andrology, which he said found that “a shorter index finger compared to ring finger correlates to a bigger ‘snozwaggler.’” “This is known as the second to fourth digit ratio, calculated by dividing the length of the index finger by the length of the ring finger,” Rajan continued. “The smaller the index finger, the lower the 2D 4D ratio. Think of it as the urological version of using one’s forearm to calculate foot size.”
