flat-topped 

Used to describe behaviour which is particularly petty, childish or vindictive in some way.

You spent two solid days arguing with 14 year olds on an Internet forum over the difference between mummies and zombies. How ludicrously flat-topped of you.

flat-topped 

1. Noun. A hairstyle popular in the early 1990s, sported by former Amiga Power journalists until present day. A haircut where the hair is shaved unpleasantly at the sides and combed straight up to form a "flat-top", a perfectly level snooker table smooth top sported above a pinch-face.

2. Adjective, "flat-topped" Obnoxious or idiotic behaviour, noticeably angry but lacking in self awareness or critical thought. Also the act of aggressively barracking one poorly thought out-idea ploughed into the ground along formulaic lines.

That inexplicably angry rant you are indulging in is particularly flat-topped, sir. And questioning my ability to 'understand simple English' is only compressing the flat-top'.
