Is there an other meaning for 'Soap'?
I was reading the newspaper today, there I found this: 
What is the use of the word 'soap' in this context? I am not a native speaker, and as far as I know, 'soap' only means the substance prepared from fat/oil that we use to wash our hands.
Soap here means soap opera.
Soap opera: a series of television or radio programmes about the lives and problems of a particular group of characters. The series continues over a long period and is broadcast (several times) every week. - Cambridge English dictionary
Examples:
- It is her proud boast that she has never missed a single episode of the soap opera.
- The new soap opera will be screened, wait for it, five times each day.
