Granted there is no exact way to tell when someone is sperging out, but when they cant keep track of their own statements, insteading spewing a bunch of contradictions as the conversation goes on based on what seems convenient to them in the moment, and clearly trying to push some emotional buttons or generally come across as way more invested and excitable (as the former two examples suggest)... it's pretty clear they're flailing

And clearly trying to defend and support a friend suggests this too. Bonus points if they try to say it's cringeworthy to go on after they've looked stupid.

That's what it was. Images to try and insult me and made no sense since he jumped in and I just answered a challenge issued by someone else (while they pretended I was begging for a debate, when really I was noting their idol ran away from someone far weaker than myself), then weird narratives about WWII which make no sense based on public opinion back in WWII or the color of the victorious nations, then pretending that WWII wasnt brought up or that it wouldnt matter what the soldiers and leaders actually thought, constantly changing from if not outright reneging on what was previously said, then trying to hit me with the suicide thing, and then saying going on is spergery, and then not tweeting for the day, liked and supported by two accounts...1 of which also didnt tweet for the rest of the day and the other being known for socks and did little to defend himself during the actual argument which started aorund him...
