Due to most definitions being incoherent here I’ll make a general one for those who want a proper
definition.
A theater kid generally is associated with anyone who does theater whether that be backstage or
front.
These individuals are generally given a few stereotypes, most commonly of which being outcasts or misfits. Elaborating further theater kids often carry or
claim to carry some disorder whether that’s diagnosed by themselves or doctors. Furthermore they are generally perceived as carrying hyperactivity from some aforementioned disorder, or being so much of an
introvert that you wonder how they
even got in the theater to begin with (though the former is often more likely)
Hamilton is generally loved by them, and politically they are often left
wing though more aligned to liberal, or if lucky anarchist leftist thought. While they
may counter and argue how radical they are, almost all would probably have a heart attack at any actual revolution due to their innate romanticism. This is because Theater kids are cosmopolitans at heart 90 percent of the time, with rural theater kids often having wet dreams of finally going to the cities away from their conservative
parents.
All in all while this is a generalization it is to give a
broad example of what theater kids generally fall under personality wise. It isn’t the best description, but it’s better than most I’ve seen here.
