grilled cheese is neither grilled nor barbequed! it's 2 slices of bread, with the outside buttered, cheese in the middle, then done in a frying pan/griddle or electric griddler, which is almost exactly the same as a sandwich toaster. so, basically, it's a toasted cheese sandwich.
they don't have 'cheese on toast' like the brits do.
tailgating - indeed named after the tail gate of a pick-up truck. not just for alcohol-infused frat boys (though that exists) but families as well. kind of like a pic-nic, but being american they do it BIG. you turn up with your truck, which is piled HIGH with the grill (unless you're at a park where there's one already), the gas for the grill, the food & drink. you listen to the game, and all wear the team colours - even your new born babe. probably there'll be a game of horseshoes or ladder ball going on.
now, can anyone tell me what the brits call it when someone drives really close behind you. i used to think it was tailgating, now i just think i've got confused.
