game boner

Something people have from being very excited for a video game before it is released.

One week before Halo 3 comes out
Person 1: "ZOMG HALO 3, OMG! I LOVE HALOO!!"
Person 2: Dude put your game boner away

Gaming Boner

An erection received while playing or talking about video games.

I wish we could keep talking about Call of Duty 3. I was just getting a gaming boner.
