Soft soap

Another typically dumb example of the vulgarised version, from Tina Baker's soap opera column in the Mirror:
To give Jimmy his due, he only talks to Lexi (proving he’s all mouth and no trousers), promising he won’t tell Carrie about her raunchy job.
If one accepts the vernacular use of the bastardised version, that might just abut be acceptable if she were talking about Eastenders - but this was about Emmerdale.
