1. Say “you guys…”
Don’t you mean “y’all”?
2. Call your cookout a barbeque.
If you’re invited to a “barbeque” up north, don’t expect any actual barbeque to be there. Don’t ask me why, but grilling hamburgers and hot dogs outside is often given the same name as that tangy delicious sauce on some ribs or pulled pork. It should clearly be called a cookout.
