What does really grind you gears? Is it those early reaper rushes? Maybe it's the proxy pylon + canon rush? Is it when you hear the "nuclear launch detected" sound but you can't find the damned dot?
Maybe it's those damned economy harrasments with mutalisks.
I know mine for sure, it's when you build your things with terran and the enemy scouters start to attack them..... You have to pull away atleast 1 worker from the minerals, stop building (most problary) for a second and start attack the scout. It's even more anoying when it starts to run and get away with 5 hp.
