um and ah

To be hesitant or indecisive, especially when speaking out loud about a decision. "Um" and "ah" are common filler words used by habit or when one is deciding what to say. Try not to um and ah so much when you're considering a counter-proposal—it's not professional. It felt like that guy ummed and ahed for five minutes before he gave me his order. Which was a burger and fries, by the way.
