Nothing says summer fun like a good ol’ barbecue. And nothing says annoying like a twosome who, well, pretty much ruins it. For the love of burgers, brats and beer, avoid inviting these duos to your own backyard bash (and don’t let yourselves become one of them).

The Grill Masters

Probably the most common type, this couple is not shy about voicing their opinions when it comes to manning the grill. Step aside and let a pro show you how it’s done. Did you know 10 degrees higher would make the perfect grill mark? That you really want to flip the burgers twice for ultimate perfection? That it’s really all about the charcoal? You do now! And don’t worry -- these helpful tips will continue well after the food has been served. “This is a good burger, but you know what would make it better?” Oh, you will.
