Who -- or what -- is LKRGAL?

Driving into town yesterday, I passed a silver BMW with vanity plates LKRGAL. I get the GAL, but what to make of LKR? Liquor, looker, locker, lurker, linker, leaker? I asked Alan at work, who is more in tune with trends than I am, and he voted for "looker." Kinda vain, even for a vanity plate, I thought, but Alan says people let it all hang out.
