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".

Get the YAYmug. Yai is a type of person that everyone loves, she will have you wrapped around her finger. She is delicate but so strong. She is stunningly beautiful, people would turn heads when she entered a room. She is full of kindness and wisdom and talents of extraordinary capabilities. She strives for what is right and puts other first. Treasure your Yai, and keep her safe.
