Tailgate parties are a lot of fun! Have you ever been to one?
I haven't actually but they are very big here where I live.  I know that tailgating originated in the United States
Interesting! Is it only associated with American football or does tailgating happen at other events?
It often occurs in the parking lots of stadiums and arenas before and occasionally after games and concerts
How was tailgating invented? 
I'm not really sure but it typically involves drinking alchol and grilling food around the tailgate of a car
It's kind of a strange tradition, if you think about it. What kind of foods do you grill?
The popular tailgate food are hamburgers, hotdogs, baked beans, and cold salads like coleslaw or potato salad.
