My ideas for the T-shirts would include personal favorite quotes from my posts, like these:

Nerd = Fat Woman
Hate is as natural as Love
Status Is Everything
Your sexual market value is overpriced.
Kitten at night, cougar in the morning.
I don’t give a shit what you do for a living.
Chick with dick = lawyer.
Celibacy = Metadeath.
Chicks dig power.
Guys dig beauty.
Marriage is a raw deal.

Or I could go hipster ironic:

I’m a beta.
I’m holding out for an alpha. (for da ladies)
I’ll be your provider beta. (for da guys)
I fall for game. (also for da ladies)
My dating market value is greater omega.
Cuckold me. It’s in your genes.

Etc.

The floor is open.

Update: Arjewtino recommended a T-shirt wording contest. Winner receives a free T-shirt and recognition in a blog post. Imagine the fame!
