Having lines shaved into your eyebrows is popular, but it can also be a sign that you belong to a gang. Some gangs use specific eyebrow designs to show membership, but if the design isn’t specific, it doesn’t mean the person is in a gang on its own.
The Southside 13 gang in Oregon cuts one eyebrow with a single line and the other with three lines to represent the number 13. Some famous people, like Vanilla Ice, Jay Z, and Soulja Boy, have shaved lines in their eyebrows.
Because they are famous, their fans follow their style. Due to the possible influence of gangs, some schools are taking the matter into their own hands and sending students home if they follow the trend.
