Excessive talking, sometimes to the point where it gets boring and
drags on for way too long, aka
rambling.
It's a slang word used in Britain, but mainly in London or other parts of England by
roadmen / younger generations.
"Bro my
Psychology teacher is so boring, they're always waffling about nonsense that has nothing to do with the lesson."
"I definitely failed that History test, I just
waffled tbh."
"That
Biology question was so long and irrelevant, there was so much waffle in it I barely knew what they were asking me to do."
