Emoticon eyes, often (5)
I believe the answer is:
colon
'emoticon eyes often' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for colon that I've seen before include "Part of intestines" , "Punctuate part of the large intestine" , "Large intestine; punctuation mark" , "cash" , "Start of one canal" .)
