Jackson/Jax
To Jackson something means you're talking about it like you're an expert, but you're just making it up as you go. It's also the guy who'll pretend he's your homie, but he'll leave you hanging when you need him most.
'I'm gonna Jackson this test, bro.' 'You mean you're gonna fail it?' 'No, I'm gonna make it up as I go!'
'Jackson, how do you know this?' 'I just guessed and it worked!'
'You said you'd help me with this!' 'Yeah, till I got distracted by my mom's yelling.'
