A turd that somebody leaves in the bowl overnight.
The expression comes from the English game of cricket where a batsman is sent to the crease with the sole aim of still being there in the monring.
I went to the bathroom this morning, and my girlfriend had left a vile night watchman in the toilet.
a man placed in the rear of a mid-night train....
My heart is breaking cus I'm the night watchman in the rear of mid-night train..
My honey I won't see again, she leaving cus I'm a night watchman in the rear of mid-night train...
Hay it's better than a trud floating in the pot....
