Does one who utters a word or a phrase of disbelief, knowing it to be a phrase of disbelief, but without intending disbelief, become a disbeliever?

Whoever utters words of disbelief, doing so intentionally, knowing their meaning, and intending to pronounce them, is a disbeliever by that, even if they did not intend disbelief. For this reason, scholars have agreed that whoever speaks words of disbelief in jest becomes a disbeliever. The proof for this is the Almighty’s saying: "And if you ask them, they will surely say, 'We were only jesting and playing.' Say, 'Is it Allah and His verses and His Messenger that you were mocking?' Make no excuse; you have disbelieved after your belief." This is in contrast to someone who errs and utters a word of disbelief without intending to pronounce it; such a person does not become a disbeliever by that.
