Example:
Bob: "Hey Tim, how's it going brah?! I just had a revelation. I realize I hate my life up to now and feel like I jumped into this marriage. I'm planning to divorce my wife and am gonna sell this stupid station wagon. Pretty badass huh?"

Tim: "Umm, Bob? You're 47 years old. You've been married for 24 years, have 3 kids and another on the way. And what does brah mean? I think you're having a midlife crisis, you might want to rethink this. I mean you have a plastic hip and a pacemaker!"

Bob: "Nah you're crazy brah, I already asked that hot intern out and put a down payment on a Corvette. Life is gonna be great. And let's keep that pacemaker thing on the downlow."

Tim: "But you'll have to pay child support, alimony, and still have your 'great life' to pay for."

Bob: "Timmy my friend, that's what credit cards are for."

Tim: "Whatever. Enjoy bankruptcy."

Example:
Fred: What's with your dad's car?
Joe: Midlife crisis.

Example:
"A man with a midlife crisis buys a corvette, a man with a lamborghini has no crisis." -Joseph "Rev Run" Simmons

Example:
He was calling the kids on the street dude and saying like a lot. It was scary.

Example:
guy 1: My dad's going through his midlife crisis
guy 2: How do you know?
guy 1: Well, he jumped out of a plane at 15,000 feet, been hitting bars every night, bought a motorcycle, bought a drumset and guitar which he cant play, and I'm pretty sure he's having sex with my girlfriend.
guy 2: He is indeed a true bro

Example:
You see that old guy on the Harley, he must be having a midlife crisis

Example:
"Wow john look at that Midlife Crisis over there"-Pat
"Ye Pat, must be about 5 of them"- John

Example:
I'm having a midlife crisis please helm me HELP! OH GOD!

****SATIRE*****

Example:
Just now, I was chatting in the room with someone I have spoken to for about 4-5 years, who is pretty much a f'ing jerk, and someone was asking him why did he change his screen name, again (since he didn't lose it to terms of service violations.) I was studying this, AND, knowing this guy from chatting with him for years, I have determined (and coined a new phrase in doing so,) that dude is suffering from Chatroom Online Midlife Crisis (COMC)
