I came across the word 'bestie' for the first time the other day. It was used on a Facebook posting of a picture of my daughter and one of her very close friends and underneath someone had added the caption 'Besties' ie. best friends.
We seem to have a habit of doing this in NZ. We start off when the kiddies are quite little by getting them to eat veggies, bickies and chippies. Then they grow up and become chippies, sparkies or posties. What other words can you think of that we shorten with an 'ie' ending?
