Jablab
Jablab is when you talk so much it sounds like you're trying to fill up a whole room with your stupid mouth.
'Bro, I swear I've been talking nonstop since the day I was born, and I'm not even done yet.'
'You just said the same thing five times, and I'm still trying to figure out what you meant.'
'I'm not just talking, I'm performing a full-blown monologue in your head.'
