Grotesque waterspout (8)
I believe the answer is:
gargoyle
'grotesque waterspout' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for gargoyle that I've seen before include "Grotesque carved figure as ancient water-spout" , "Grotesque carving" , "Medieval gutter spout made of sculpted grotesque figure" , "Ugly person's" , "Ugly carved figure on a building" .)
