It's not even a consistently American thing.

I (from Texas) use "couple" to mean two-ish-or-more whereas my wife (from New Mexico) uses couple to mean exactly two.

I use "couple" to (roughly) mean "just enough in small amounts" like:

- just a couple more minutes (obviously doesn't mean 2 minutes and 0 seconds)

- grab a couple of glasses (probably two unless there are three people)

- buy a couple of things (I'm making a short trip for a small number of things)

For those decrying using imprecise language, it's because these are scenarios where enumerating would give an incorrect level of precision.

I'm being informed by other Aussies that it's not consistent here either, lots of people seem to use it imprecisely as well. I'm actually a Kiwi (but have lived the most recent 15 years in Australia) so it seems I've been misinterpreting the Aussies for years...
