Her shirt says, "Keep Adjusting Weird"

I cannot help but wonder what this shirt means to her? As far as our culture, here in America, goes, her looks are nothing particularly "weird" even to Vandy Frat. standards. She's wearing neon-chartreuse hued taffeta-like workout shorts, the shirt is grey with red lettering, and her long brunette locks are sloppily tied back in a black hair band. She sways from side to side as she saunters out the door in her "old" flipflops and her painted dark pink toenails presented as she points her feet outward.
Here is Rusty. He is around 5' 5" with gray hair and a perpetual frowny face with thick gray eyebrows and a thick gray mustache. He always wears either a red or white t-shirt. He used to go straight to the beer cooler and get 2 6-pack of Amstel Light and 4 Grolsch singles. As we rang him up he'd say in his gruff unpleasant sounding voice, "I need a buey-suee too" which meant he needed a B.C. powder packet. He suddenly stopped buying beer one day and we asked him about it, 'I changed my reeligion" he told us. And....that was that. He's a bit odd..even for JJ's. He has a pepper farm and he lives in the middle of Downtown Nashville - around 2 blocks from JJ's.
What I want to know is - if one is "weird" by choice, and not because they are just who they are, is that then "weird"? What does this shirt mean? What is "adjusting weird" and why does it need to be adjusted? Are people like Rusty, who do not know that they are "weird" the ones whom she is speaking to or about? Or is she speaking to the fraternity and serority people around her? I want to design a shirt that says, 'Weird can stand on its own feet" and give that to her ::smiles::
