Pet peeves are (by my definition) things that make you feel like the unidentifiable yet decidedly provocative @$!#% symbols in comic books IRL.
There will never be enough side eye to denote the frustration I feel when someone walks slowly in a busy place. Obviously it's understandable to walk at a leisurely pace if the location you are trying to walk through is crowded to the point of near immobilization, but if you are just frolicking aimlessly in slow-mo I'm assuming you're the worst human to ever exist and are purposely there to make my life miserable.
Other things that grind my gears are loud-chewers, cyclists who speed by with no warning and when people don't say please and thank you.
But enough about me, what are your pet peeves? What makes you want to scream "dang flabbit" to the world??
