Concerted Game 

1. Antonym of cockblock.
2. Spitting game about how awesome you are, but more importantly, how good your friends are.
3. Taking one for the team when necessary.
4. Making sure everyone gets some that night, at (almost) any cost.

Look, there's three girls and three of us. Instead of all trying to hook up with the hot one, let's use concerted game! Alex, you get the fat friend while Andy and I will flip a coin for the hot bitch. The loser will get the intellectual.

Conceited asshole 

Someone who is strongly proud of himself or his accomplishments.

Chris said that he could do 3 times more push ups than Ædôn could. So Ædôn called him a conceited asshole.
