\ ˈtē-ˌshərt ˈbȯis\ n. A member of a volunteer or paid-call fire department who never shows up to training. This member also never responds to calls, even though they may be less than a mile from the call. These members are just in it for the fire department t-shirt.
Well it's Thursday and none of the t-shirt boys have showed up for training.

There was a call one block away from one of the t-shirt boys house and he didn't even respond when Active 911 showed him as being home.
