The lazy day belly usually refers to
girls, it happens when wearing any outfit but usually on the lazy day outfit. It's those few inches of your stomach that shows, not from
fat, but simply from your shirt riding up and you're too
lazy to pull it down.
Having a lazy day
today, nothing like a tank top, sweatpants, hair tied, and
chilling with no make up on. Oh and it seems i have some of the lazy day belly too
haha.
