Having a long continuous bowel emptying shit.....
A shit that is in the water before it leaves your arse...
The opposite of "dropping the Cosby kids off"
Example 1: Wife - How long you gonna be...what are you doing in there?
Hubby - Fuck off, im Laying a cable
Example 2: Worker - back in a minute, just going for a shit
Boss - you going to Lay a cable
Worker - nah, just dropping the Cosby kids off
