A lot of terrible gift ideas for guys have been born out of the completely inaccurate notion that if guys love two things, they'll love those two things put together. This is how bro-tastic products like bottle openers that play orgasm noises happen, and they are asinine. But then there's the BoomCooler, which, as the name suggests, is the combination of a cooler and a powerful boombox, and it is the rare "combo" product that is an undeniable stroke of genius. Not only does it combine two things that are absolutely essential for any outdoor party, but it uses extremely high quality components so that the beer really gets cold, and the music really gets loud. And that, folks, is what a good idea looks like.
