Speaking of legendary, digitally-stammered catchphrases, the greatest one of them all has to be this one from Unreal Tournament. While every time the super-low-pitched announcer vocalises one of your head shots or combo kills is extremely satisfying, none can compare to his announcement that you've earned five kills in quick succession. The phrase is perfectly suited to your achievement, and distinguishes itself from each of the kills leading up to it (Double, Multi and Ultra) by that stammer, which makes it sound like the game is on the verge of breaking down because of your sheer murderous awesomeness.
