(obsolete, except possibly regionally) to slurp; to drink noisily
(informal) to talk or speak unnecessarily lengthily; to talk idly; to engage in unsubstantiated talk; to babble

When Peter is in a good mood for once, he won’t stop babbling for the rest of the night.
(colloquial) to chat; to talk among each other (usually about light topics); the verb retains a certain nuance, but becomes rather neutral
