Brain

A pink thing inside our heads that nobody seems to use anymore, especially in math.

Teacher: C'mon it's easy just use your brain.
Student: What the fuck is a buh-buh- brai-brain? Like what even is yo.

Brain

The faithful dog belonging to Inspector Gadget and his niece Penny. Brain is Penny’s sidekick, and helps her on missions. Brain has human level intelligence, and can do things that normal dogs cannot, such as ride bikes and use tools. Brain has saved Inspector Gadget countless times. He loves his human comrades, especially Penny. Brain will do anything to protect his humans, and usually endures astounding amounts of punishment. All he wants in return is the company of Penny, and food.

I would love to have a dog like Brain, and a daughter or niece like Penny.

Brain

To hit someone in the head with a blunt object.

Regan, Kennedy, Morgan and Aziz were sitting in Bon Vivant, celebrating Regan's birthday. She opened the present from her aunt.
"OMG, she gave me beautiful vase." The others agreed.
Regan picked up the vase weighing it with her hand.
"It's a good thing Cassidy ain't here" Regan still weighing the vase in her little hand. "Otherwise I'd brain her."

Brain

The next generation of the blowjob...which became "Suck my Dick," then "Give me head," and finally morphed into "Give me Brain".......because, as we all know, brain is better than head. Think about it.

You might have to take a good looking woman out to a nice dinner in order to get head...... but all you have to do in order to get dope brain is get her to sit in the passenger seat of your shitty ride, flex the stereo, lite up a cigarette or a blunt and help her along with your hand on the back of her head.
