When you have consumed copious amounts of alcohol at a wedding/party and you take a short nap whilst the party carries on around you. After 15 mins or so you awaken with new found energy and enthusiasm to dance.

The act of sleeping on someone who is weaker than you,

A five to ten minute nap during a night of hard partying to revive your energy and party on.

A power nap is a means to continue through your tough day by taking naps at 20 minute intervals AT MOST. in fact it is what keeps you going during pledging. if you sleep any more than 20 minutes you might as well call it quits.`

To tell your mum your going to have a power nap, often after a meal, when your actually going to have a wank

sleeping on top of someone that is weaker than you
