Brickstone 

When you are doing anal with a girl and fisting her in the vaginal area at the same time.

Me: Bro when i was screwing my chick I decided to give her a brickstone and I broke my knuckles.
Friend: Woah your hardcore! I gotta try that!

brianstorm 

When a dyslexic or a group of dyslexics attempts to create solutions to a problem by spontaneously suggesting ideas.

"Why is Professor Turner writing down his favourite Arctic Monkey songs on the board?"
"No, he's trying to write brainstorm, let's see if he notices."
"Brianstorm is a great song, though."
"Aye, it is mate."
"Are we pirates now?"
"Aye."
"This all seems unnecessary."
"Arrr, I'm just brianstorming."
"It's just a bit confusing in the context of a urban dictionary definition. Also, someone needs to fix that fourth wall."
"Let's add that to the list."
"This is stupid now."
