Russian Concussion 

The Russian Concussion is when you are balls deep in a girl and smack her on the ear so hard that it starts to ring. Then, while she's holding her ear in pain, you cum inside her.

I was having sex with my girlfriend the other week and she told me to slap her, so I gave her a Russian Concussion.

Pre-Concussion Shake 

A mix of ingredients put together to prepare your noggin for the biggest, most fucking gigantic concussion this green world can give a person.

The ingredients of such a shake are unknown to humankind and every living species in a milky way.

Recently though, a man known as Aziz Walid Alghawas has recently found out the ingredients to the pre concussion shake and continues to keep the recipe to himself.

"Bro, did you know Aziz sponsored Conor Mcgregor with Pre-concussion shakes for the rest of his career?"

"JFK was supplied with a motherload of pre-concussion before he was...."
