Sticky stuff (3)

I think it could be either:

goo

sap

'sticky stuff' is the definition.
(goo is a sticky substance)

This is all the clue.

(Other definitions for goo that I've seen before include "Anything sticky" , "Sticky gunge" , "Slime" , "Sticky substance (colloq.)" , "Sticky substance (sl.)" .)

I've seen this clue in the USA Today, The Star Tribune, The Mirror, The Guardian, the King Feature Syndicate, The Wall Street Journal, the Universal, The New York Times and The Times.
