The term "bat out of hell" has been incorrectly used for decades. It is actually "Bad out of Hell". As in "They were coming out of there like the bad out of Hell." As if someone opened the gates of Hell. My grandmother used to say this and she was born in 1902. And, think about it....... there are no animals in Hell. They cannot sin.
having a wank, every bloke knows that if u don't blow ya load at least once a week your spunk goes bad inside your balls, leading to rashes, insomnia, shivers, madness & death!! So by getting out the 'bad seed' you are promoting healthy living.
I couldn't bloody sleep so i had a wank & by getting out the bad seed i was able to snooze soundly.
