Be conspicuously unsuccessful (2,4,4,1,4,7)
I believe the answer is:
go down like a lead balloon
(Other definitions for go down like a lead balloon that I've seen before include "Be conspicuously unsuccessful (2,4,4,1,4,7)" , "Be spectacularly unsuccessful (2,4,4,1,4,7)" , "Be spectacularly 7 Down" , "Be poorly received" .)
