"yais" can't be defined conventionally. one would be less successful at defining "yais" than he/she would be at defining the contemporary english language's utility infielder, "like". "yais" is a state of mind. "yais" is understanding and misunderstanding, as well as all points described on the subsequent continuum.
you are lovely, yais; gay, yais; yais? yais; is two plus two, four? yais; (if i had the character spaces to continue, i probably wouldn't. yais.)

something that can be expressed best with full on vibes. this term is a bright and shining light, of super goodness, that beams out of your solar plexus and third eye, when filled with joy and happiness. it will then saturate anyone or anything that is open to such frequencies, and the YAY will be passed on and on and on. hugs, songs, winks, smiles, snickers, any happy receptive touch, are all great examples of YAY stimulators. YAY!! it just feels good...
