Miracle flush
When you've clogged the absolute fuck out of your toilet, you resign yourself to go get the plunger, and then, you hear a sucking sound, and the water flows through your pipes and out of your bowl as it compelled by a higher power.
Man, I clogged the hell out of my toilet after I ate that bad burrito, I was praying for a miracle flush but I ended up just getting diarrhea all over my arms when I plunged the damn thing.
