Wear Something Gay.
"that shirt looks hella gay"
For some reason there still exist individuals who are under the impression that it is ok ("cool" even), to purposefully hurt others. Physically, mentally, verbally - if its hurtful, it's bullying.
This shirt is inspired by the arbitrary nature of calling someone's piece of clothing "gay." The actual image on this shirt is not a reference to anything gay, nor does it symbolize queerness. It is simply a cool design. There is nothing "gay" about this shirt, aside from the fact that the word "gay" is indeed printed on it....
Reclaim what has traditionally been used in a derogatory way. Take that phrase that's meant as an insult to the wearer, and well, wear it.
A Bully: "that shirt is kinda gay.."
You: "well, yes. Yes, it is. It is quite gay indeed. What of it?"
