Yeiss is a word for "Yes" That is used by alot of newfoundlanders who have a real newfie accent and is over used by newfoundland rappers. Kids in NF will start to say it around Juiner high and then will not nitice there saying it anymore.

The British form of the word "yes". Can be spelled "yeis", "yace", "yaise" but never "yase". Usually said by thick-accented Brit folk.
