Fertilize the Fertilizer 

The act of ejaculating into the toilet after you've finished making a #2, either as a type of kink, or because you didn't feel like flushing it first.

Guy 1: "Hey bro, I'm gonna go fertilize the fertilizer 'cause I'm too horny to bother flushing my shit first!"
Guy 2: "Too much info bro, but alright!"

Fertilize the clock 

The same as milk (or milking) the clock,
but while you are staying on the clock beyond the end of your shift you are in the bathroom taking a long dump.

Are you going home right away?

No that burrito I had for lunch is talking to me.

I think I am going to stay for a bit and fertilize the clock.
