snap at

blow up boil over erupt rampage roar seethe tear

bristle chafe fret fulminate fume overflow rant rave scold scream splutter steam storm surge yell

be beside oneself be furious be uncontrollable blow a fuse blow one's top fly off the handle foam at the mouth go berserk have a fit have a tantrum let off steam look daggers make a fuss over rail at rant and rave throw a fit work oneself into sweat

be calm

be quiet compliment flatter praise

be happy
