Definition

A verbal shrug that merges 'hmm' and 'what?'—the audio equivalent of tilting your head while squinting. Perfect for when someone's statement is so confusing or unbelievable that you can't even process a full response.

Example Usage

My coworker explained his weekend plans so cryptically that I just looked at him and said 'hmwha?'
