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 Wall Street Journal, The Mirror, The Times, The New York Times, the Universal, The Star Tribune, the LA Times, the Penny Press, the King Feature Syndicate and The Guardian.
