Plurality

[lelandfe]

Plurality is more common in the US, while relative majority is preferred in the UK: https://en.wikipedia.org/wiki/Plurality_(voting)

...Although Brits tend to be familiar with "plurality" in my experience, while Americans tend to have no clue what a relative majority is (judging by the downvotes of the GP, it looks to be holding true).
