Frineds Black T-Shirt
Yes. I want to be FRINEDS with you. Do you want to be FRINEDS with me?
Smile when your friends and colleagues and other people you know question the authenticity of your shirt. Cooly raise one eyebrow and say, "Oh it's genuine." leave a long pause [like longer than a pause should be. make it way too long and then count to five in your head] and then say "and if you were a real FRINED you'd know that."
That being said, because I said colleagues and other people you know that bit doesn't really work but you get the idea.
Available while they are available.
