I've complained more than once on Styleforum website about how younger people pronounce vowels, specifically how they pronounce the letter i as if it were u. For example, they say "uhnnterestuhng" and "Uhllinois." Well, this bad pronunciation habit completely ruined a flirting. A lady was talking to me in an amorous style when she said "I've been told I have great tuhts." I probably shouldn't have, but I just got mad and was like "what the hell are you trying to say? Why do you talk like that?" From that point on, everything was ruined.
