It is almost certainly a nigger.
I don't know why they said it was underaged. In the niggerhood, once the nigger escapes the larval stage and is no longer considered to be a potential ghetto lobster, it is ready to begin a life of crime and muh dikkery.
To calculate the age of a nigger, advanced math is often needed. Here is how I figure things out.
x = Nigger's age in nigger years.
y = Nigger's age in human years, minus z.
z = First 3 years of niglet's life, in human years.
z=3,y=4,x=43
z+(y*10) = x
So in this case, if the niglet is 7 years old in human years, it is actually 43 years old in nigger years. More than old enough to be committing crimes, and old enough to be punished for them.
The average lifespan of a human in human years is 81 years. The average lifespan of a nigger is 60 in nigger years.
