A person that lives at multiple firehouse in an effort to actually make it above the poverty line in the EMS world. Normally they are EMTs, but paramedics and firefighters have been know to adapt this behavior in lower paying arenas.
Also; when a rival fire company takes a call out of district. The would not be dispatched on the initial call, but would mysteriously appear as "the closest unit." When confronted; the normal response is: " well, we gotta eat, too!"
Damn firehouse squirrels.
C15 totally squirreled that call.
Get out of our district you damn squirrels.
I'm just a squirrel looking for a nut!
