It's hard without specific examples, but brusque or somewhat impolite generally seem common. For example, someone asserts something technical in a strong way, lacking technical insight, or re-animating a zombie topic. The response is often short and somewhat acerbic. To be honest, replying in a sensitive way, with references to past converations, takes a long time. I would contrast this with jerk as being someone who deliberately disregards the comfort and feelings of others to satisfy themselves: the queue jumper, Steve Jobs, someone who humiliates people on minimum wage, who doesn't re-rack the weights at the gym, who parks in the disabled car park.
