The weird and oddly warm wind that blows through the Muni Metro tunnels platforms in San Francisco. Its origin is unknown but it is probably created by the trains moving through narrow tunnels but also sometimes appears without warning and out of nowhere.
"I'm underground, dammit, I shouldn't have to fight the wind! But this damned muni wind wont stop messing up my hair."
