This is an easier way to say you have to pee ( #1) and take a shit (#2) at the same time. You create a nuclear explosion in the bathroom called the 8 bomb. Once you take a #8 you know you made a mess.
If you are taking a #8 you are dropping tons of shit.

Mark 8 nuclear bomb.
I have to take a #8.
I just did a #8 bomb.
