A girl who hangs around Military bases and tries to get with the Male personnel who goes on leave. They usually have older cars to drive them around in and usually know what days thier leave is. When they get with them, they usually settle into a romance and try to baby trap them. Some just like hanging out with guys in the military and for others, it's a scam to work into making the guys take care of them. Navy version is Shore Rat
Damn, those Army Rats never give others guys a chance but, they will do whatever these guys tell them to.
