This is a gravid belly. /botebara/

It means something along the lines of a bulging, swelled-out abdomen. The word generally refers to the belly of a pregnant woman.

Starting today, you mean.

At least make it tomorrow...

And I've warned you so many times too, Agano-nee. Now you ended up with a bloated stomach that can be mistaken for a pregnant woman's, thanks to your frequent unhealthy lifestyle choices.
