tag magnet
A person, usually a female, who has a record of dating multiple military servicemen. Different from a tag chaser in that a tag magnet doesn't "chase" these military suitors, they are "chased". Defined by the accidental track record for dating of military men rather than seeking them out, as well as lacking ulterior motives related to dating these men due to their jobs.
She's a tag magnet because she's dated a few marines, but the marines are the ones that chased her.
