12月是節(jié)日氛圍最濃的一個月份，圣誕過后就是新年，大家都在忙著為朋友和家人準備禮物。這一準備不要緊，禮物越買越多，帳單越積越厚，到該還款的時候才意識到透支了不少。

Christmas buzz is a feeling common during the month of December. It is the need to buy many overpriced gifts for your family, normally on a credit card. The buyer feels no feelings of regret for the rest of the month, as he/she feels they are being a good person. The Christmas buzz is always followed by the New Year's hangover, when the credit card bill comes in and the buyer goes on a rant about how much money they have spent.
Christmas buzz（圣誕沖動）是12月份很常見的一種情緒。它會讓你給家人買很多超貴的禮物，而且通常都是用信用卡結算的。買的時候一點也不會為這個月剩下的日子擔心，因為你買這些禮物的時候覺得自己是個好人。緊跟著圣誕沖動而來的就是新年怨悔，那時候信用卡的帳單也該寄來了，你才會為之前花出去的錢自怨自艾。

For example:

You're buying a Nintendo Wii off eBay for 500 dollars for your kid? Must be the Christmas buzz.
你要在易趣網(wǎng)上花500美元給你孩子買個任天堂游戲機？一定是圣誕沖動了吧。
