words or phrases no longer used ironically

Words and their meanings and the way we bandy them about change like every other day. Certain sayings are a small definition of an era. Often what is the hip lingo of the moment quickly turns to a vocal embarrassment.... such as hip lingo. Half of the syntax we knew has become abrasive and rude, which is far worse than passé. Who can keep up? Most of the banter spoken these days are all abbreviated letters that look like Algebra, So confusing man... dude... people.

Redditor u/TheeTeo wanted to discuss what parts of language they've changed relationship with by asking.... What's something you started saying ironically, but now say unironically all the time?
