knock your walls out

To have sex with someone who so tight it feels like your knocking the vaginal walls down with every thrust.

Physically I would love to knock your walls out but mentally I’m just too tired.

hard knock life

From the film Annie............. Basically it's shit being ginger and walking that scrotey dog. But in reality in 2012 - it's even worse thinking back to the bald headed fucker that adopted me & my dog! Dog = vets , myself = rape counsellor!

Cost me £80 fucking quid to sort my dog out and my bums still well sore - its a hard knock life!
