3. An elderly person who rambles on but has no idea what they are talking about.

Nutty Old Bat:
Are you even old enough to know what fidelity is?

Random girl:
Aren't you a little old to be causing drama on facebook?

Nutty Old Bat:
i'm just a few years older than you, and I am not causing drama on facebook. Do you even know what drama is?

Random girl:
Just a few? I took you for a nutty old bat.... that's drama ::

Nutty Old Bat:
No nuts on me my dear.

Random girl:
That's a shame. What business do you have messaging me, by the way?

Nutty Old Bat:
I won't even lower my dignity with an answer to your question.

Random girl:
What dignity? It was apparent you had no dignity when you chose to rudely message a stranger and throw out a pathetic attempt at being witty.
