To be fair, now that I think about it I high fived some random dude at a summer festival in my hometown (we have a lot of summer fests) because he was wearing a HL&TN shirt and my wife thought I was being a jerk and making fun of him. I was had to reaffirm that "No, I in fact, think that shirt and the band being advertised are rad as ####."
She's knows I'm serious when I call things rad.
