Bedgasm

Definition: a feeling of complete and utter euphoria which peaks when climbing into bed at the end of an 18-hour workday, a long road trip or hours of extremely strenuous physical activity.

当结束了一天18个小时的工作、一段长途旅行或数小时极为疲惫的体力活动后，爬到床上后所产生的那种彻底难以抑制的幸福愉快感。

E.g. It was a three hour drive in the middle of the night, I could barely stay awake. When I got home, I climbed under the covers and had a ten-minute bedgasm.

大半夜的连开三个小时的车，我实在是很难保持清醒。当我到家后，我爬到床上钻进被窝，彻底享受了10分钟的身体放松愉快感。
