What is some of your Pet Peeve's

The keyboard...
Who came up with the bright idea to mix up all the letters?

Back in the last century the mainframe we were on at work had the ability to remap the keyboard via the login procedure (a macro), so I did so for about a half-dozen guys - laid out their keyboards in alphabetical order. When we migrated to PC LAN-based ERP software as part of the Y2K transition that ability went away. There sure was a lot of teeth gnashing and caterwauling from those guys.

I'd put it in the same category as calling vegetables "veggies" or mayonnaise "mayo". More annoying modern slang than peeve.

Calling a shotgun a "shotty" makes my skin crawl.

Why? You don't call a rifle a rifey or a pistol a pisty. And it's not like you're saving syllables.
