From the linked article, regarding ideas to boost attendance at A's games:

Then maybe a day for the Crosby Shrieker, a woman who shows up most of the time and calls out "Bobby You're Hot!" unless he makes an out, in which case she changes it to "That's OK, You're Still Hot!" Since Crosby went on the disabled list, she has shifted to a Juliette Binoche-ish "Bobby, Where Are You?" cry, which fluctuates between heart-wrenchingly plaintive and profoundly unsettling. This is devotion that requires a bobblehead, or at least a T-shirt giveaway ("I'm Mildly Disturbed For Bob").

So, is he talking about BobbyCrosbysGirl? An arch enemy? Sorry, the answer may be common knowledge, but I live way out in the boonies (Tokyo) and never get to go to games, so I have no idea who he's talking about.
