Translate sucks, but what I think is being said is:

First panel she calls someone offscreen “trash”, and they say “if I’m trash then how about you be a trash can” and she says “huh?”

Reality shifts, the scene:

“Hey, wanna eat lunch to- omg are you a trash can? Lucky!”

“Yeah, that’s right, I’m stuck here today and can’t move, so I can’t eat lunch with you sorry”

And the guy putting trash in her is like “there we go” or whatever, and his friend says something about something being popular I guess. Maybe being a trash can is super popular? I love reality warp logic.
