Is this someones style of written communication, rather than verbal? You use LOL a few times, so maybe this is a writing style.
I've met people who are like this in real life. I don't know if there *is* a specific English word. "Jerk" is a good start, but not specific enough. There are other types of jerk. Same with "idiot". For the people I've met, "irritating" or "insufferable" are words I would use. But then I get accused of taking things too seriously and being jealous of someone who just likes to "ave a larf".
In a way, it's much like most men talk when they're in the bar with their mates, anyway! I must confess to having been in situations where everybody spent the whole evening trying to "talk the most idiot talk". Something to do with men being afraid to admit they care about anything, I guess.
So, after much contemplation, the word your looking for is: Man. LOL LOL LOL
