A person who lacks the ability to continue a story after being cut off in the middle of it. Generally a dankwanker
will become unnecessarily angry and lash out at those close to him, so that he
will then be left
alone to relieve himself indignantly.
"Hey
man, did your buddy just cuss you out and leave?"
"Oh, him? Yeah he's just being a little dankwanker
today, he'
ll get over it."
