Term used by ppl who can't reason well but wanna feel like bosses, to indicate that instead of working to improve themselves, they'd rather lower the standard of discourse so they can compete.
Person 1: *makes a claim that they cannot possibly defend, and the reason they believe it is probably because of a bias *
Person 2: why do you think this?
Person 1: You are such a debate bro

Someone who has figured out how to make a living by appealing to teenage bros who couldn't tell what a sound argument looked like if it hit them flat in the face, as exemplified by the most popular entry on this page. Such youth believe that the more insults and taunts are crammed into a sentence, the more effective a refutation, especially when paired with WWE heel style self-praise and a loud, masculine voice. The movie Idiocracy inevitably comes to mind.
Debate bro fan - Brah, did you watch ToughCommieHooligan last night? He DESTROYED that liberal professor!
Educated youth - No. How did the professor lose?
- Well you know, TCH said he had a mosquito level I.Q. He also laughed very loudly every time the professor tried to respond. It was carnage!!
- Okay...

A synonym for sophist. One who argues in "bad faith".
Jimmy kept arguing that the Earth is a flat square made of cheese and used a priori axiomatic presuppositional post-rational empirical multivariate and fuzzy logic to justify his position. He must be a debate bro.

A spin off on the term ‘Frat Bro’ expect in context of academic debate. A ‘Debate Bro’ will out of their way to make sure everyone knows how smart they are at post-modern philosophy, international relations, deductive reasoning, and other obscure topics while simultaneously shaming other debaters for their lack of expertise in said areas. A ‘Debate Bro’ ruins the fun of academic debate for others and proliferates the toxicity of exclusivity, racism etc. within the space.
John “Dude, wtf you haven’t read DnG’s 1000 Plateaus? You should, you’d win so many debates with the information in it”
Jason “Dude, stfu, you went 2-5 last tournament, stop being a ‘debate bro’.

Snarky-laden term used by Leftists to describe Conservatives/non-Leftists that make them look bad in debates. The definition of "Debate" is fairly straightforward, and "Bro" is a not-so-coded way for feminized Leftists to signify to its audience that it's a part of "toxic" masculine culture.

Leftists want to ascertain that they're right on the issues, but Conservatives override their "correct" substance by being more "dominant" or "assertive" in a non-substantive way. They're trying to make the argument that Conservatives are "strong but wrong", while Leftists are "right but weak". Truth is: Personality doesn't make you more correct when you're wrong. It's only liberals who fail to prove Conservatives wrong in a particular issue.

The term was only coined by Lefties as a cope phrase to justify losing and/or failing to defend their weak positions and embarrassing themselves to the point they no longer want to "engage" in debate. Just look at every debate Daily Wire or TP USA event
Blue-Haired Feminist Leftist at Ben Shapiro event (talking into a microphone) - "I think the the gender pay-gap only exists because of sexism, and thus why we need to end the Patriarchy."

Ben Shapiro - "Actually, the so-called 'gender pay-gap' doesn't exist because of discrimination. If you take into account skills, experience, tenure, willingness to work overtime, and take less vacation time, that perfectly explains why men out-earn women. Plus, it's pretty counterproductive for a company to pay women less on average, but hire more men on average, if pay is all that mattered."

Blue-Haired Feminist Leftist at Ben Shapiro event (talking into a microphone) - "OMFG, fuck you, you sexist piece of shit! You're such a Debate Bro if you really think I'm going to stand here and listen to your so-called 'facts' and 'deductive reasoning' to justify your misogyny and make me look bad! And you probably don't get laid either! INCEL!"
