'Labern' (to ramble) is a colloquial word and has a clearly negative or derogatory meaning. It expresses that you consider someone's talk unimportant, boring, or stupid. Use it only in informal situations.
Er hat die ganze Zeit nur über das Wetter gelabert.
He just rambled on about the weather the whole time.
A very common fixed phrase is 'jemanden volllabern' (to talk someone's ear off). It means to talk at someone nonstop, often about unimportant things, so that it bothers the other person.
Laber mich nicht voll, ich muss mich konzentrieren!
Don't talk my ear off, I need to concentrate!
You can simply use 'labern' (to ramble) on its own, without an object, or you can use the preposition 'über' (about) plus the accusative to say what someone is talking about. Both are very common.
Die beiden saßen auf der Bank und haben einfach nur gelabert.
The two of them sat on the bench and just rambled.
