If one does not visit the toilet regularly or has a bad case of the shits aka brads aka Diarrhoea they may find themselves in a situation where there is "Panic at the gates". One wet fart and it could be new pants time.
Man after that curry there was panic at the gates

When in an work situation your boss demands that you have a report on his desk by yesterday you experience panic at the gates. A high pressured work deadline.
The manager called in yesterday and wanted my project outline by tomorrow! Panic at the gates!
