Well there are two ways this someone else can kick me out.

1. We have some advisors/extremely-early-investors so any two parties that band up together, have the majority share and can throw the third party out.

2. This someone else has been footing a lot of the bills for the startup because they could take on other projects while I worked on the product. Because the we agreed to mostly split the bills halfsies and I didn't have the money, the other cofounder payed for me and now I owe him the money. He is now requesting I vouch for it with a big enough share of the company so he'd hold the majority share.

Also, as mentioned, we're both in the company on a reverse vesting thing - this is so when problems occur, people can be thrown out without taking half the company with them (ie. better for the company, not for the persons)

And that's basically how someone else has the ability to kick me out.

Then you need to settle with the other guy and one of you needs to leave with a small share of equity for time served.
