In my posting on Einstein quotes in Zippy, I referred to Einstein as a “quote magnet” (using a felicitous expression from Fred Shapiro) — that is, someone who attracts quotes (meaning that quotations from other sources are attributed to that person).
The X magnet pattern for ‘someone or something that attracts Xs’ is a snowclonelet, the model for which might have been chick/babe magnet, used to refer to someone (a guy, or sometimes a girl) or something (a car, for instance) that attracts women. A few examples:
Want to be a Chick Magnet?
How to make any woman want you (link)
Solar electric car a chick magnet? Wall Street Journal Uncovers ZAP Xebra Xero (link)
It’s Official: The Tesla Roadster Sport Is A Babe Magnet (link)
From chick magnet came dick magnet, referring to someone (a girl, or sometimes a guy) or something that attracts men. As in:
[Theory of a Deadman, "Bad Girlfriend"] My Girlfriend’s a dick magnet, My Girlfriend’s gotta have it (link)
There are probably also examples of dick magnet ‘someone who attracts dicks, i.e. jerks’. Certainly there are examples of jerk magnet:
Are You a Jerk Magnet? … You’ve been known to attract real jerky guys from time to time (link)
No doubt there are more X magnet examples, for other X, out there.
