An exclamation denoting amazement, surprize, awe, disgust etc. Krykie is heard most often in Austrailia.
If you just heard that a giant beaver ate a whole city, you would probably reply “Krykie!” or “Gee Mate, ya don’t say”.
Or, if you just got speared in the chest by a sting-ray's barb, you'd probably shout, "Krykie!" or maybe just, "kryk! " or, "kr!" --Still too soon? Sorry.
