chengqi's answer is correct. 朋友圈第一条点赞 means the first Like/Upvote on the post of your Friend Circle in Wechat. Let me explain more about "条". When "条" is a classifier(量词) in Chinese, it can describe many things. (NOT only used for long things.) (1)To describe long SHAPE things 一条河 one river 两条烟 two cases of cigarette 三条鱼 three fish 四条街 four streets (2)To describe human body 一条心 one heart (MEANS like-minded/teamwork) [Sorry, this one might be too difficult to understand] 两条人命 two lives (3)To describe something abstract 一条微信 one Wechat message 两条意见 two advice 三条新闻 three news stories

It's mean your are the first one to 'Like' or 'Upvote' your friend's post(just like Facebook Twitter Ins).

经常会看到的，微信（Wechat)里有人经常会说朋友圈第一条点赞，就是他的第一条动态需要你去点赞。就比如ins或Twitter发的动态差不多。
