Saying Hindu Words

Aslaamualiakum

A wife watches an Indian program. In the Indian program one of the actors keeps saying ‘my God/oh God’ in hindu. The wife finds it quite funny the way it’s said.
At times the wife ends up saying what the actor says in Hindu.
Does the wife saying this make her a kaafir?
The wife has no intention of kufr and does not beleieve in the Hindu sayings.

Jazakallah
