What does the circled text mean?

I don’t know. Waiting for an answer!

Bass (the bassist) ate (did well) house down (impressive)

It's gay/queer slang. Ate (and sometimes 8 since they sound the same) refers to someone doing something very skillfully. Ate the house down is a different way of saying that which sometimes also implies they did better than everyone else. Bass is just referring to a specific person and is not part of the phrase. Edit : it's usually the house down not house down. That's not really a correct way of saying it that way but it gets the point across well enough so it doesn't really matter.

This is gay slang. Ate means did well, as in “Oh she ate that performance up.” Idk how to explain house down. It means whatever this means: https://youtu.be/YNYKP7_POBg?si=frLkI-L_Y8rhvN9p

Not a native speaker, but I've seen "eat" being used with the meaning of "was successful" in slang.

This is pure conjecture, so stay with me: “___ brought the house down” is a way to say a performer (in this case a musician) succeeded greatly. on the other hand, when you say “____ ate” you mean that they did something impressive. The commentator is combining these two phrases. In addition, they use Bass to mean Bass Player. So, all together, we get: *The Bass [Player] impressively succeeded in their performance*

To "bring the house down" means a performance so good that the applause causes the building to collapse. Not literally, of course, but figuratively. An amazingly good performance. https://www.collinsdictionary.com/dictionary/english/to-bring-the-house-down https://dictionary.cambridge.org/dictionary/english/bring-the-house-down I suspect that this phrase is an adaptation of that. "Ate" is often used in modern vernacular to represent an action. "Bass" is presumably referring to the instrument.

It means someone either misused or mistranslated a slang term, "Burning the house down" -- a phrase for someone performing beyond expectations. (It is a phrase usually used in the context of performance arts.)

It refers to the fact they are a Three Doors Down cover band

I might be wrong, please correct me if I am. I use to read that people nowadays say "she ate" to say, for example, that she was succesful on doing an activity, that she is "killing it" or performing something super well. In this case the bassist learned the song super fast, so she did something awesome. The person who wrote that could also have said that they really liked the way the bassist played their part, the feeling she put into it or whatever. So, she did something awesome or that you liked, then you can say the basist "ate", "she ate". I don't know where it comes from. The following part I think is just an exaggeration: "the house down". "She ate" so much that she ate the whole house down 🤷

ate = did well house down = kinda difficult to explain, but its like an exemplified, sort of a "no lies" statement. both lines come from queer/ballroom subcultures

Sorry, I'm still stuck on poop-kaden.

It’s slang. Sometimes saying “you ate” or “that eatsss” is a way to say to say like you did good, better than good tho. Like “that was f*cking awesome” or “you did that!”. But “ate house down” just means they killed it.

I haven't the slightest idea.

I'm a native speaker. I have no idea what this means.

They’re saying the bass player was good. Saying something/someone “Ate” or “eats” or “served” etc. all are complimentary statements.

bass did better than everyone else

There is a mainstream English idiom: "He brought the house down", meaning that he gave a performance that was so good that the audience's thunderous reaction threatened to bring the house \[performance venue\] down. This seems to be a recent variant of this idiom: Bass \[the bass fiddle player\] ate \[brought\] (the) house down.

The bassist was the best of the bunch and a standout compared to the rest

The text at the bottom explains it.
