For each subreddit, we only consider terms that: • are used at least 10 times in the subreddit; • are not present during the first 3 months of the community's existence; and • are introduced within the initial quarter of the community lifespan.
we restrict our analysis to newly introduced Internet slang terms that are not present from the very beginning of the community's activity, but are not introduced too late so as to be able to observe their trajectory for a substantial period of time.
