Pass round sticky stuff (3)
I believe the answer is:
goo
'sticky stuff' is the definition.
(I've seen this before)
'pass round' is the wordplay.
'pass' becomes 'go' (synonyms).
'round' becomes 'o' (round can mean a round object).
'go'+'o'='GOO'
(Other definitions for goo that I've seen before include "Sticky wet material or sickly sentiment" , "Slime" , "Sticky or slimy substance" , "Sticky and slimy stuff" , "Sticky matter" .)
