Peak Momentary Power Output. It is a marketing term that means little in reality. It is the absolute max power that the system can put out for a theoretical perfect millisecond or so.

Only pay attention to RMS power output.

It means Bull *@#%

Well... actually it mean Peak Music Power Output... which means nothing in the real world.
Even the smallest speaker can have like a 400W PMPO.

The true measurement of power is the RMS rating in Watts. (Root Mean Square)

For example a 15W RMS speaker is rated at 450W PMPO.

Any Hi-Fi enthusiast, like myself, only ever goes by RMS... in fact... if the products has PMPO listed on it.. it's probably not even worth looking at, because they're just trying to sell you a pile of junk.

Momentary, such as during the very peak of one very loud drum hit, for example.

A system can be something like 10W RMS, but 200W PMPO. It's the 10W that matters.

It is usually only used with cheap speakers to fool people.

According to the Glossary (Google for PMPO) it is actually Peak Music Power Output. This is in contrast to RMS (Root Mean Square) power measurement in audio amplifiers.

I have a mini-component from sony it claims to have 1500W PMPO, and a friend of mine has one aiwa which claims to have 2500W PMPO.....My sony demolishes it totally.
