Age and sage

And that’s how you get good rose wine (oh, and a dash of lemon).

While looking up what 下敷き meant, I (quite randomly) came across:

上げたり下げたり

and a shortened(?) form 上げ下げ (agesage).

I guess this is where the imageboard terms age and sage come from?

Disclaimer: I haven’t actually tried my wine like that yet!
