LOL, what he means by his suicide threat is, "my mom once again told me to get a job and made threats to eventually kick me out if I don't, and I told her that if that happened, I'd kill myself, and she said, 'sure, whatever,' so REMEMBER THIS AND AVENGE MY DEATH!"
I kind of get the feeling that maybe Jake's suddenly got competition for mommy's affection. Reading between the lines, it sounds like there's now more frequent pressure to move out. I imagine if new Stepdaddy Alley came into the house and started interrogating Jake about his job application activities on a daily basis in exchange for Jake continuing to be able to have a roof over his head, this is exactly the way Jake would act about it on Twitter.
What Jake really means about killing himself is that he'll step in front of a car someday if he ever has to sleep rough. The thing is, and I know I'll get optimistic ratings but I'm dead serious, I have known people who endured multiple bouts of short- and long-term homelessness, and I literally do not think Jake has what it takes to prostrate himself to all the people who he'd need to beg for services from. I don't think he has the ability to shut the fuck up and take charity.
I think he absolutely will kill himself if he's kicked out of the house, because he's really that lazy and vindictive. He'd really show his mom and her new boyfriend then! Plus it'd mean he'd never have to get a job.
He's literally the cow on the site who I think would make the least negative impact on literally anyone by dying. His mom will finally be able to move on, after a period of grief, and can maybe sell the house and move somewhere without so many gnome memories. No one else alive would even care. Bex and a few of the other troon crowd would be delighted to have a new suicide flavor of the week and they'd howl about GamerGate and KiwiFarms. For a week. Then his name would be forgotten.
