The correct phrase is "harsh their Mellow".
I think you mixed it up with"kill their buzz"
I wouldn't know, just heard "them " say it.
Also I feel compelled to point out these are Neo Hippies and not "regular" Neos are easy to spot and until recently could be seen wearing hats with similar colors as the flag of Ethiopia or a Che Guevara t shirt or both. At least that is the criteria the police use. Most of them will give a quizzical look when questioned about the Lion of Juda or the adventures of Che before he took the Marxist thing too far in Bolivia . This is the key to separate genuine and poser
