The 'Frog or Rat' trend gained traction on TikTok as a playful way for users to categorize their facial features into two distinct aesthetics. 'Frog faces' are generally characterized by wider-set eyes, rounded features, and a soft, approachable look, while 'rat faces' feature sharper, more angular structures, prominent noses, and a more edgy or chic vibe. Unlike traditional insults, these labels are used affectionately within the beauty community to celebrate diverse facial structures and niche aesthetics. The trend involves users posing or using photo comparisons to determine which category they fall into, often sparking lighthearted debates and self-deprecating humor among followers.
