It happens with the full moon at perigee. Since it is at its closest point to the Earth in its orbit, it looks bigger and it also has a stronger effect on tides.

It’s a full moon that coincides with the moon being closer to earth due to its elliptical orbit.

And it’s a misnomer. It’s only a few percent larger than a “regular” moon.

See diagram At perigee the moon appears 14% bigger and 30% brighter than at apogee.

The Moon is not in perfect orbit around the Earth. It is occasionally closer, and occasionally further away. A Super Moon is when it is full at its closest point to the Earth.

It could also refer to Chris Christy, after losing his swim trunks when he performs a dive.

It’s a fad on facebook. The moon is never as huge as they pretend it is on face book and it isn’t a rare occurrence either.
