As I said in the OP, it seems to just be me.
Thought I'd let you guys get some giggles about the ridiculous levels he reaches on some of these barbs.
While discussing a plant that I've kept alive for ten years (which I thought was pretty impressive) "Oh Lisa can grow anything. She has houseplants that are as old as she is and they just thrive!"
While discussing books "Oh Lisa reads much better authors. She has such good taste in literature."
While discussing an outfit someone else complimented me on, "I'd never choose something like that. It's not flattering on you at all. Lisa's sense of style is so much nicer."
While discussing an online game that everyone got hooked on for a while (I had gleefully told my score to someone) "Is that all you've gotten? Lisa made 54, 4478 points in just two hours yesterday. I guess not everyone can be good at that sort of hand/eye coordination stuff."
While discussing a stupid trip to the grocery store! "Lisa is a much better bargain shopper than that! She always saves us at least 50 dollars at the store and we eat like kings!"
And here's the real kicker- I was talking to a friend who asked me about my crocs, which are tan he said "Lisa doesn't wear those ugly things. And if she did, I'm sure she'd pick a more lively color. Tan is really unoriginal."
The croc thing really got me. I was like "Dude, they're plastic shoes! Who cares?" to which he said, "Well, women should always be conscious of looking cheap."

I thought, whoa, did he just call me cheap? Then my friend asked him that exact thing at the same time Dh walked up and asked what we were talking about. Dh, who also had on a pair of tan crocs! John changed the subject.
