Ok, coming from a country that has 11 official languages, with most people able to speak at least 2, we have some very odd quirks.
"Hey" can mean multiple things... Hey? = Excuse me, just Hey is uused to emphasise something... eg. Wow, that was a big dog hey!
"Lekker" pronounced Lacquer means nice, or tasty (it's taken from Afrikaans)
"Cherry" means girl... "That was a lekker hot cherry hey" ie "that was a hot/good looking woman"
"Eish" (pronounced Ayshe) taken from Zulu is used as a symapthetic word, or even as a filler... Bob says: "I fell down yesterday" you reply with "Eish"
We have tons more I will add as I remember
