Lay A Brick 

To excrete one's faeces;

For one to lay poo-poo

To 'Lay A Brick' is to drop a hefty turd

My whole family came round to my house for Sunday Roast, and a couple of hours later i had to 'lay a brick'.

My dick is so hard I could lay a brick 

Having a fully erect penis, that is so hard and ready for sexy time, that it is totally capable of pounding even solid brick to smithereens.

Holy Shit! My dick is so hard I could lay a brick! That's right, I could literally pound the virginity out of a solid brick! So, anyway, what's your mom doing tonight?
