Yikey Spikey! 

An utterance usually indicating shock or amazement, a variation of yikes but with a harder edge. A session browsing the pages of UDwill often cause this expression to be ejaculated with frequency.

"Yikey Spikey! So that what a pink sock means! I just thought it was hosiery of a pastel colour!"
