A non-New Zealander person overly obsessed with anything related to New Zealand/Aotearoa (a mix of the word weeb and kiwi).
"This guy has been talking about going to New Zealand the whole day! It's like they never think about anything else!"
"I know right? They're such a kiweeb"
Used to describe Kiwis (New Zealanders) who live is Wales, or Welsh who live in New Zealand. Also used to describe rugby fans who support either team, depending on who's winning.
Mate, it must suck being Kiwelsh, both the ABs and the boys in red got a hammering in the semis this weekend
