To be "balls all week" is the correct term to describe the corolation between a time span of the begining of the week till the present and the feeling which can be described as energetic or hyped-up.
Dave: dude, quit doing that!
Allen: don't tell me what to do man, ive been balls all week!
Dave: oh, ok. I didn't mean it.
No balls week starts December 9th and ends December 13th. You and a group of friends or in a pair come up with bets (saying no balls) and you have to complete the bet. If you don’t complete you own the other person or people who gave you the bet something. Loser owes all or one person something they really want.
Friend: Yo it’s no balls week. No balls you’ll tell your crush you like him.
You: balls I can do it
