It's some Finnish meme. They post a picture of a bastardization of pedobear and say it's "ebin" or "e/b/in" because "epic" is wordfiltered on the big Finnish imageboards.
Imageboarders get upset by it, in which case you just remind them that pedobear himself is a bastardization of a Japanese character, and that 4chan has had its fair share of zany catchphrases.
