From Wikionary: "To intrude on a conversation with disingenuous questions in an attempt to engage in unwanted debate as a form of harassment."
From Macmillandictionary.com: "In an online conversation, repeatedly asking a person questions or making comments which suggest that you are interested in what they are talking about, but are actually intended to annoy them"

The reference is taken from "WONDERMARK: A Collabroation With The Dead" web comic #1062; "The Terrible Sea Lion"
"Becky is being a real Sealion, like, no one wants to debate her wack-ass and she won't take a hint."

A word used for calling people out online who repeatedly target others with exhausting questions.

Or

A shady, made-up word that can be traced back to one text from the most exclusive university Harvard, within a country that has the death penalty, in order to divide activist circles across the English speaking world with its double meaning.

‘Sealion’ so happens to be an excellent excuse and reason for humiliating someone online. Performative activists need to create new words and labels for people, where if you only replaced these words with good old curse words, you’d be witnessing clear online harassment.
Person 1: …” What proof do you have that I’m speaking to you in bad faith”?

Person 2: “’We’ don’t have to prove anything, I’m ending the discussion, this is ‘sealioning’ YOU ‘sealion’”!

Person 1: “Why are you making the point of calling me a ‘sealion’ when you can just block me…”?
