Someone that I was involved with many moons ago. Was fine to go out with. The evening would start off lovely, until the drinks came out, even then, he was fun then he would pick up on one thing I would say and make a huge song and dance about it. Once, he stood up so sharply the table with all our drinks on it toppled over and he left. Another time, he threw a drink in my face and, left leaving me there sitting with everyone looking. That was the last time I ever went out with him. It was years ago.
Recently he has been spotted in a hotel bar throwing a drink at his companion, running off to their room, her trotting after him and the whole hotel being kept awake with him screaming at her.
Another time, he was sat with a woman and my friend and her husband sat with them, they had a lovely night until he turned around to this woman and said "who are you, do I know you?" and flounced off to his room, her following him and then arguing all night.
What is the name for this sort of bloke appart from wanker is there something more psychological going on?
