look up any word, like hipster:
 
1.
A custom shirt made from CustomInk.com approximately at the cost of $25.

The shirts competition is the image the wearer chooses to put on the shirt.
Say you were to see a picture of a tumblr quote with a nice background. If you were to download it, you could go onto CustomInk.com and put it on a plain color shirt, and buy it for $25. This would be a C.I. Shirt.

"Friend: Where you got that shirt at?"

"Me: C.I."

"Friend: Damn it's a C.I."
