Chalk the bowl

After taking a dump (likely large in nature), and flushing the excrement, if marks are left on the toilet bowl from your shit, you have successfully "chalked the bowl", and multiple flushes may be necessary to remove your prize or possibly a scrub of the toilet brush!

I like to chalk the bowl after a huge meal of Indian curry chicken.

Don't get them.
They're lame.
Enthusiasts use them for rock climbing.
Make your own.
You will look cooler

"Haha, Gavin is holding his chalk sak while he climbs!"

Rock Chalk

Something that is definitely going to happen, there's no doubt about it. It's guaranteed.

If Scott and Jamie got into a fight then it'd be rock chalk that Scott would K.O. rickshaw Jamie.
