A party , usually a family party, where the male host requests that the guys bring two cars so their significant others can leave with the kids, and the guys can stay and get shitfaced and shit.

The careful "consulting all people involved" verification that you'd jolly-well better perform before you accept any paper financial-instrument from anyone, especially if the document is "signed over" to you by the document's original payee!
Performing a two-party check is vital to maintain your financial integrity, not only because you might not get paid, but also because you could get hit with a returned-check fee and other legal hassles if the check is either drawn on an account with insufficient finds or is written without the account-owner's authorization.

1. When the company or employer you work for, doesn't provide an annual Christmas party and an employee(s) throw it instead. "Unconventional" meaning you're invited and can invite your friends, family, co-workers, etc. and your friends can invite their friends, family, co-workers, etc. For some people, their jobs do not have Christmas parties anymore, or they are never asked to one, this remedies the lack of festive celebrations.

The general rule of thumb for attendance, once you are invited, you can invite anyone and then they can invite anyone. Someone should invite you before just showing up. Note: Everyone should pitch in similar to a potluck or a globally set amount to pay for a venue and food.

2. A Christmas Party hosted by anyone but the employer, primarily for their fellow employees. This Christmas party can include, but not limited to, their friends, families, significant other's co-workers and their friends and family.
John: Hey, my job can't afford to pay insurance to throw another Christmas party. Let's have our own "Unconventional Christmas Party!"

Jane: I'll try not to all go to jail for inappropriate behavior this time!
