These terms appear to be rooted in the sense of cap as “top” or “upper limit.”
History lesson: In the 1940s, according to Green’s Dictionary of Slang, to cap is evidenced as slang meaning “to surpass,” connected to the ritualized insults of capping (1960s). This meaning of cap dates back to the early 1900s. To cap about something is “to brag,” “to exaggerate,” or “to lie” about it. That'd be a nice one, but to bullshit a forum with access to search engines that can easily prove I personally didn't make this up lol Just highlights that you are willing to be disingenuous with your arguments at any cost, which in turns exposes that you're willing to act like your core argument didn't exist, as you acted as if the word 'cap' didn't exist. 'I'm aware of the term, but to actually use it is another thing entirely'
This would've been a better response, I'll help you out, something along the lines of: It seems you deviate towards some weird gas lighting technique, acting as if things we all know exists, doesn't lol unfortunately i'm not your romantic partner, gaslighting isn't going to work here you started off okay, but this isn't your best. Man you must be running out of steam, this is poor work.
