Today I got 2 hits by the same Georger, about a minute apart. I'd spent 4 Georges at Starbucks this a.m., and I assume this person got 2 of them.
So, what are we going to call this, if anything? Best I can think of offhand is "multiple hit," and I don't think that quite conveys that it's simultaneous (or close to) hits by the same person.
