When you know someone is taking a shit, you run in the bathroom during the shit and you yell,
"ARE YOU TAKING A SHIT?!"
and the other person will prob be like,
"GTFO"
and you say in a high pitched voice.
"BUSTED"
then exit the bathroom.
After you complete the task completely, you are now officially a shitbuster.
*Friend Goes Into Bathroom and Sits Down To Take Shit*
*You wait 2 minutes then run into bathroom*

You: "ARE YOU TAKING A SHIT?!"

Friend: "Yeah GTFO BITCH!"

You: "BUSTED!!" (In High Pitched Voice)

You are now officially a shitbuster.

Get the Shitbuster mug.
The bathroom version of a ghostbuster. Shitbusters flush any toilet that still has shit in the bowl. Shitbusters that flush leftover urine in toilets and urinals are called pissbusters.
I just saw a shitbuster flush all the toilets in the public bathroom at my local McDonald's.

The act of having an involuntary orgasm while in the process of taking a shit.
This morning I took a dump and, out of nowhere, I jizzed at the same time...I think I did a shitbust!
