1. To walk or hike in some place, especially in a meandering, lighthearted, or carefree manner. We always love to traipse in the woods behind our grandparents' house when we were kids. Make sure you are well prepared before you go traipsing in the mountains with your friends.
2. To arrive or enter (some place) in a careless, thoughtless, or flippant manner. We were all supposed to be in the office by 8, but it was nearly 11 before Tom came traipsing in. She traipsed in the door the next day as if nothing had happened the night before.
