Messy liquid substance (5)

Ross

I believe the answer is:

gunge

(Other definitions for gunge that I've seen before include "Nasty and sticky stuff" , "Sticky mess" , "Unpleasantly sticky or viscous material" , "Thick sticky muck" , "Unpleasant sticky material" .)

I've seen this clue in The Mirror.
