Incongruity: (noun) having a lack of conformity or harmony, inconsistent
Incongruity: A motorcycle pulled up to me at a stoplight this evening. The man on the bike had on a black leather jacket, a leather skullcap and a bandanna over his face that makes him look like a grinning skeleton. I noticed loud music coming from stereo speakers built into the bike.
His head was bobbing along to Ricky Martin's 1999 pop hit, "Livin' la Vida Loca."
