Snowman could be so abhorrent! (10)

I believe the answer is:

abominable

I believe this is a double definition.

'snowman could be so' is the first definition.
(as in the Abominable Snowman)

'abhorrent' is the second definition.
(thesaurus)

(Other definitions for abominable that I've seen before include "Hateful" , "Very bad, terrible" , "Atrocious" , "Odious" , "Causing moral revulsion" .)

I've seen this clue in The Telegraph.
