pushing flannel 

When you have to take a shit so bad that it's popping out of your asshole and pushing into your flannel underpants.

I drank to much free coffee during that training session and now I'm seriously pushing flannel.

Fuck Flannel 

Similar to a Cum Rag. A fuck flannel may not infact be a flannel, it is purely an amount of cloth used to clean up male ejaculate.

"Hey stop wiping that on my curtains! Use your Fuck Flannel!"

Cum Flannel 

A crusty piece of cloth or sock used to wipe ejaculated semen from the chest of a man who has just engaged in onanism.

Or

A person lacking in intelligence, who has as much use to the human race as material used to wipe up ejaculated semen.

You absolute cum flannel.
