Nov 27 Word of the Day
A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.
That fucking smooth brain put his shirt on backwards again...

That smooth brain is dumber than a pile of shit.

The funniest, craziest, party game on the market. (Oh No You Didn't card game) This game gives your team 20 seconds to guess four words. 5 points for each correct word. Get them all right in 20 seconds and you keep the points. Miss one, and the whole room of opponents start wagging their fingers and shouting, "OH NO YOU DIDN'T." But, in order 2 take your points they must first pull a "Challenge" card and follow the rules on the card. (Miss a turn, Add 5, 10, 15 points to your score, Take 5 points from each team, etc.) They then have to pull a "Word" card and have 20 seconds and MUST guess all four words correctly. If they miss all four, every one is laughing, finger wagging and shouting Oh No You Didn't to them. If they get them all in the 20 secs, they get 20 points and take the other teams points. (15, 10, or 5 points) First team to 300 points wins the game. Crazy laughter, and accommodates up to 40 players easily. The ultimate party game.
We had a great time playing OH NO YOU DIDN'T at our house Friday night.

1. A word used when your girlfriend just found out her best friend has been sleeping with you, and her brother, and her out of town cousin.

Usually it results in a cat fight in which she slaps the bitch and they start rolling around slapping and pulling hair. While Guys stand around watching waiting to see some panties. unfortunately most of the time their panties reveal a dark secret... Mr. Happy! Then you decided to pull your so called 'girlfriend' and chuck her out the plexiglass window.

2.See Don't go there girlfriend
1."Oh no you di'n't!" "Oh yes I did!"
"Oh really?" "Really!" "F-cking skank b-tch go suck your mother's hairy -ss. You stupid chauvnistic c-nt licker!"
