After the 'thighgap' phase and the infamous 'bikini bridge', the latest trend doing the rounds online is the 'finger trap test' which tells whether they're pretty or ugly.
According to News.com.au, the test is based on the 3.1 ratio theory used by plastic surgeons for the "perfect profile" and requires you to place your index finger against your chin and nose to see if your lips touch it.
If it does touch, then only are you in the attractive category.
Despite the idiocy of the phenomenon, it is trending very much, especially among women.
