I've run across these terms several times, but without enough context to figure out what they mean. Could someone help me out, please?
ETA All of you are amazing! A huge thank you to everyone who responded, and an extra thank you to those who have provided links or explanations to further and/or related information. I am learning so much by reading all of these comments!
One thing about sealioning that I haven't seen mentioned yet is that it's a tactic designed to utterly exhaust the other person by asking question after question with no willingness to listen to the answers. It's there to waste time and grind down your opponent until they have had enough of your bullshit and tell you to fuck off. At that point you can feign offense and declare victory.
