When you drink so much, it's literally as if you hit your liver over it's tiny head with an alcohol mallet and it has a concussion.

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.
