The-Umm-Uhh
A filler phrase used by pretentious twits in an attempt to increase the amount of time they can hear their own voice. Only used by the most self-important of people with feigned intelligence.
Well, according to the-umm-uhh hypothesis presented in my superior argument, the interstitial atonality of my voice is umm-uhh extremely irritating. Presently, I should um-uhh terminate my life force after realizing I'm a fucking idiot.
