Originating from the movie titled "Johnny English", this phrase is used when all other vocabulary is lost, and nothing else can be thought of to say.
When somethings bad happens, it could be used as an alternative to swearing:
"I've gone and pissed me self, oh frebib"
"I've gone and pissed me self, oh frebib"
