  • “Imma gonna go ahead and block TexasSkeleton as a bad faith sealion, but thank you for engaging with them!”

Randi's list is a key reason I've been able to continue to use Twitter, as it prevents relentless ideological sealions from crowding my mentions.
For parents

"sealion" means: One who engages in sealioning.. This is informal slang, common in casual speech, texting and social media, but not appropriate for school work, applications or professional settings. There is no real cause for concern in itself; it is everyday peer vocabulary. If your child uses it, a light comment about audience and register is usually enough — no need to escalate. Context, more than the word, tells you whether to follow up.

For ESL learners

"sealion" means: One who engages in sealioning.. Register: informal slang, fine in casual conversation, texting and social media but not in academic essays, business writing or formal speech. A common non-native mistake is to use the word in the wrong register, or to assume one fixed meaning when it is actually polysemous; always check the surrounding register and the audience before producing it yourself. In formal writing, prefer a neutral synonym or a short descriptive phrase, and use this word only when you have heard or read it being used naturally in a comparable context.

  • “This whole thread made you look like a sealion. It doesn’t make you look good at all. Even a little bit!”

  • ““Just asking questions “ #Farage #Sealioning en.wikipedia.org/wiki/Sealion...”

  • “You didn’t “sealion” or hurt anyone”

There, Peggy speaks for every angry marginalised person who’s ever been sealioned or tone-policed in a disagreement.
Origin: The verb is from “[http://wondermark.com/1k62/ The Terrible Sea Lion]”, a 2014 strip in the webcomic Wondermark, in which a character expresses a dislike of sea lions and a passing sea lion repeatedly, intrusively asks the character to justify this.

For specific readers

"sealion" means: One who engages in sealioning.. This is informal slang, common in casual speech, texting and social media, but not appropriate for school work, applications or professional settings.

Why is this section here?

Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
