Used in the place of "yes" yay-eee-s
Expression used to acknowledge a comment that is exceedingly odd or beyond the listeners level of understanding. Also used as a way of providing an answer without actually answering anything. Often one may incorporate a pause as to create the illusion that they are actually thinking of a valid answer or comment. One may also use "yais" as a way of covering up his/her daydreaming while in a conversation. For an example of how to say "yais" properly listen to tom hanks in the movie "The Terminal".
