commungeicate
Someone who, talks AT you, by interrupting you, trying to finish your train of thought, then asks you, "What are you talking about?" After a couple of repeats, you just trail off while being admonished for not knowing what you're talking about. Communicating with an ASS eating.
They just commungeicate at you and won't let you finish the story. Com-munge-i-cate!! ( obsolete mange to eat )
