It is when you underestimate something you did, which is really challenging to others as if it was nothing so that you sound like you are modest and don't want to flex, but in reality, you are just flexing implicitly.
-So I forgot the formula during that test, but I derived it quickly by neglecting the value of "such and such" and canceling "term" with "term" to derive the formula in a not-very neat fashion XD, gosh I'm so stupid!
-Bro, stop anti-flexing.

-I was getting bored lately with the Java syntax so I made my own programming language, it is a stupid language tbh.

Act of flexing (/flex) or low key boasting over the fact you played classic wow, also known as vannila wow, an original world of warcraft.

Trying to assume superiority over your peers in a current non-classic expansion, because you assume nobody else ever could have possibly played classic like you did.
Preferably over raid and group chats and voicechats with as many people as possible involved.

It also has a memeberberry effect, when people pile on, to prove they "know the lingo" and "were there too" which eventually turns into an endless circlejerk which then occupies discussion, till broken up.

It is not to be confused with general private reminiscing over outdated WoW content.
Classic Flexer 1:"Classic was better and I played it so I am better too, let me tell you why you all live normies suck, but not me, cause I am only here till classic..."
Classic Flexer 2:"Oh remember when we had to drink water? Aw yeah, classic was SO DAMN GOOD!"
Classic Flexer 3:"Ugh, this expansion sux, remember when, in the good old vanilla wow ..."
Classic Flexer 4:"HAHA! Right guys, NAXX was the sh!t, this dumb raid has nothing on it!"
Raid Leader: "Jimmy , would you kindly shut the fuck up and do /pull 10 and follow these "oversimplified" boss mechanics properly?"
