Do you want relatives over on Christmas? / Because that's how you get relatives over on Christmas.
A Archer meme.
Archer is Sterling Archer, the vain, reckless secret agent of the animated spy comedy Archer. His recurring line - "Do you want X? Because that's how you get X." - became the template: "Do you want ants? Because that's how you get ants." It's the meme for snarky cause and effect.
