Maybe it means:

$$\sqrt{\frac{-1}{64}} = \frac{\sqrt{-1}}{\sqrt{64}} = \frac{\sqrt{-1}}{8} = \frac{i}{8} = i~~over~~ate$$
You could see that the 8 on 2018 resembles myself who eats a lot...

• I'd even suggest "I overate before 2018" – Teun D Jan 2 '18 at 11:32
• @TeunD or "at the start of," considering yesterday was the beginning of 2018. – maxathousand Jan 2 '18 at 14:22
