In a very boring sense, "I'm wearing socks" is constructed, in that wearing, socks, and maybe even I are arbitrary labels.
Still, you didn't construct the meaning yourself when you read the sentence. It was constructed by society, and you appealed to that context to interpret what I meant.
You might respond that the social context under-determines the meaning of words. That's true. But even so, we mostly understand each other in ordinary conversation. At that level, Phil Goetz's question is meaningful (if not particularly interesting to me).
I just noticed that if I hover my mouse over the big green dot with my total karma, it says, "81% positive". Presumably 81% of the votes on my posts and/or comments have been positive.
I checked out the % positive for everyone on the all-time top 15 list:
Average = 90.6%, Standard deviation = 4.93%
So I'm 1.95 standard deviations below average for the top 15. Not only am I at the bottom of the list, we would expect me to be at the bottom of the list of the top 39 users. (Assuming these numbers are representative of the top 39 LessWrong users, which is dubious, and that LessWrong users are "normal", which sounds even more dubious, 97.44% of them have a higher upvote/downvote ratio than me.) I've gotten about 6744 down-votes, a bit more than Alicorn's 6711, but still second to Eliezer's 15225.
How should I interpret this? I could say that I'm the most-controversial poster on the top 15 list, and be proud of that. But if I'd had the highest %positive score, I'm sure I'd be proud of that, too. As long as I'm extreme in some way. Or if I were closest to the average, I suppose I could also be proud of that.
Before checking, would you guess that the top 15 have higher, or lower, % positive scores than most users?
