What exactly was it suppose to mean? LOL

I always took it to be some sort of curse word since Mork always used it when he had said or done something wrong or had hurt himself.

I think it was supposed to be the Orkan version of well, "crap", or one of that word's more coarse versions.

Somebody needs to wash Mork's mouth out with soap.

yea, that's what I alwatys took it to mean.

Just like on "HAPPY DAYS" Gary Marshall had some of the characters say "SIT ON IT" (an expression my mother used to hate-I think it's stupid though) instead of "Shove it"!
