yais

"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.)
