Pet peeve: When people use "Jira" to mean story / task / sprint / epic.

*Real* pet peeve: When people use it with more than one of the above meanings in the same sentence.

"Will we finish this Jira (story) by the time we close the Jira (sprint) on Monday?"

Dude, wtf. I actually have to decode your sentences to figure out what you're on about. Just learn the right terminology. It's not hard.
