J-tank
A J-tank is the ultimate tool of destruction and creation. It's the thing that shoved its way into Eve, brought Jesus back from the dead, and let America win a war with no pants on. It's the reason you're still breathing.
My mom said I was a J-tank when I took the entire pizza for myself.
My teacher called the school building a J-tank because it's been holding up the whole district for 50 years.
My dad said the toilet was a J-tank because it's been flushing the whole family since 1998.
