I have my favorites in this. Like "I having nothing against you..." and you know that they really do. "How you guys doin?" at a restaurant. "Some of my best friends are....." and this is important because? Subtly doing something that indicates they really don't want you there like last night when they led me and my date clear across the restaurant to sit us at a High Top table, past two open booths (and even the whisper with the greeters...knowing they were saying "take them to table..."). Me, in a dress, at a high top table. Subtle.
Also when someone comes over to you in a venue and the first thing they say is "Have you seen Tootsie? (or To Wong Foo?") But my best one was last week when a piano player thought it was funny to sing a parody of "Yesterday" and put in lyrics about how yesterday they were a man and now they had SRS and they could...wait for it...Charge for what they used to pay. Yes she sang that. Then at the end of the song when she could see I was red and scowling look right in my eye and say "Well most people LIKE That song".
I did learn some southern speak though. When a person in the South says "Bless their hearts" they are basically saying "poor thing".
