Basic Trope: When someone responds to another person complaining about their problems by bringing up their own issues, with the implication that the other should be grateful that their issues aren't as bad.
Straight: Bob complains to his buddy Dick about his recent problems dealing with his twoLove Interests, Alice and Eva. Dick responds by revealing that his last date stole his wallet and went on a spending spree with his credit cards, leaving him struggling to recover his finances.
Bob complains about his girl problems. Dick proceeds to rant about how he lost his own girlfriend, his house, his job, his father disowned him, he's living out of his Alleged Car, and is barely scraping by and wishes he only had to deal with a couple of hot girls fighting over him.
Dick is trying to sympathise with Bob by sharing his own worries, but it comes across as trying to one-up him.
Dick as problems, Bob has problems, Bob isn't aware of Dick's problems so he has to bring them up.
Inverted: Dick and Bob each try to prove their Stiff Upper Lip is stiffer than the other's.
Dick: Oh, come on, Bob! Your problems are so trivial, I can't believe anyone would complain about them. Ask yourself this: who do you want to spend your time with, Alice or Eva? Then ask her out.
Bob: Look, it's not that easy. What if it turns out badly? Dick: What, like your date lifting your wallet and charging ten thousand dollars on your credit cards? I'm telling you, you're worrying about nothing.
Bob: Alice and I broke up. Charlie: I just got some bad news from my doctor. Bob: She was cheating on me! Charlie: I have cancer. Bob: I only found out, cause she gave me AIDS! She's only HIV positive.
Averted: Dick lets Bob vent without bringing up his own issues, even if they're comparatively worse.
Enforced: Bob is far less stoic than Dick and it would be out of character for him to not complain. However test audiences found him too whiny so they threw this in to give him good reason to be quiet.
Lampshaded: "What is this, a contest?"
Defied: Bob realizes that his issues are lesser compared to the epic trauma Dick suffered through. Dick is sympathetic and points out that just because he suffered worse doesn't mean Bob's suffering is any less real.
Discussed: "You know, it feels like I can never talk about my problems to anyone, since there's always someone else who has it worse than me, and expects me to just forget my problems and expect me to feel bad for even bringing up my problems. I'm really, truly sorry that your husband is an alcoholic, or that you're drowning in debt, or that your sister is in the hospital with a broken arm, but I wasn't aware that this was a "who's life is the worst?" contest. I'm sorry."
Deconstructed: Dick refuses to show any sympathy for Bob's problems, and Bob stops telling him about them, even when he really does need help dealing with it all.
Played For Laughs: Dick replies to Bob's lament with "You think that's bad! [Laughably Minor Complaint!]"
Played For Drama: Up to this point, Dick hasn't given any indication that anything was going wrong with his life. But Bob's complaining about his laughably minor-by-comparison issues has finally pushed him too far, and he snaps, revealing all his issues and calling Bob on never asking how he was doing.
