term used when someone's talking up such a storm the whirlwind of words doesn't even make sense anymore and they just damage your braincells, sometimes permanently different levels exist, but generally every time someone devolves into a yapnado, it's always an EF5. EF0: this yap sesh won't fucking stop EF1: this guy is starting to make my head hurt + EF0 EF2: reversible cognitive damage from yapping EF3: not so much reversible anymore EF4: won't shut up, takes your topics and yaps about them too, feeds off of frustrated listeners EF5: everything above plus the added bonus of permanent cognitive dysfunction and neuron scouring - the yap sesh is so bad your neurons actually undergo apoptosis
