The coke bottle is magically autorefilling all the time (no it's not beer so no worrys)
And his stomach is autoemptying(??) Or maybe he's just constantly pissing. Maybe those breaks are him pissing in the bottle and drinking it all over again? Would make sense since there wouldn't be any magic happening then.
I hardly recognize this as a weeb meme, but that's about it. Life is difficult, having a weeb avatar, and weeb people mistaking you for a weeb, when in reality you are very unfamiliar with the so called "animes" and the culture surrounding them...
But who am I to say, I guess. The expression is an in-joke by itself.
