The ancient process of removing the contents of a backpack, turning the bag inside out, re-filling it with its contents, then waiting to watch the expression of confusion/disbelief on the bag-owner's face when they see what some loser did to their bag. However, it is thoroughly amusing.

The term was derived by the appearance of a "heatwaved" bag, which looks like a Dominos Pizza delivery bag.

Made famous by the thayer academy class of '07, particularly Artie and Slider.

A well-known DJ from Essex.
There was supposedly only one reason the name was given to him,
It is said that 'Heatwaves' are both Kool and Hott at the same time,
and so the name was happily accepted and therefor he switched from what was his previous name (Dj Trinity).
Hey Sandra, did u get 'Unleash the Heat', Dj Heatwave's new MixTape?
