As an experienced English speaker, I thought I’d offer this list to beginners and those wanting useful phrases for conversational English.

• Yankee Doodle — This is any American, especially a silly one
• If that plane leaves the ground and you’re not with him, you’ll regret it. Maybe not today. Maybe not tomorrow, but soon and for the rest of your life. — This is how Americans encourage others to make good decisions and live their best life now.
• I have two guns, one for each of ya. — A friendly greeting for border patrol agents
• Gentlemen, you can’t fight in here. This is the war room! — A way of asking someone to repeat themselves, typically said forcefully
• You know how to whistle, don’t you? Just put your lips together and blow. — One of many compliments for American women
• Yellow-bellied, toffee-hearted, lily-livered — Also compliments
• Why, Johnny Ringo, you look like somebody just walked over your grave. — A friendly greeting for any pastor, parson, or priest
• We’re going to need a bigger boat — Americans often say this when food is placed before them.

All right. That’s all you get for today. Go have fun and don’t drive on flooded roads.
