Urban Dictionary is a wisdom of the crowd. The most upvoted entry is sometimes a troll or funny (if the latter: let's say we disagree on taste of humor). As another poster said, need to be cautious, and read multiple entries. Or simply don't use it unless you don't have another source (this word is in the dictionary [1]).
Calling someone woke is discrediting the other person. Its like a signal to other people (especially the people who also often use this word), 'this person is politically aligned with X, this person cannot be right'. Its an insult, but so is the term 'wappie' (used in The Netherlands for people 'who don't believe in corona'). Faggot (when not in UK referring to gay person), nazi (when the person clearly isn't). These are all examples of insulting terms. They're polarizing. Even calling someone a communist when they clearly aren't is insulting, because communism is historically related to dictatorial regimes as well as purges (Stalinism comes to mind).
If they call themselves a communist (or a liberal, or a conservative, a nazi, woke, or whatever), fair game. But calling someone else that way when they did not identify with such is uncalled for. Because you put them on a political spectrum, with all kind of strings and assumptions attached to it.
Now, interestingly, calling someone a nazi or a faggot gets you downvoted or banned on most forums, but with a term like woke people still get away with. Not sure why.
According to Google Translate, pretentious translates to pretensioonikas in Estonian as the most popular translation, so it seems like it got borrowed from English (not implying it originates from English, I don't know about the etymology).
