this word orginated from a random college party when all of a sudden strangers started to show up. the strangers pretended that they knew someone at the party and said they knew the "harnos". not knowing what the word "harnos" was, we automatically let them in. so if u nerds out there need automatic entry to a party, let them ppl at the door know that you know the "Harnos"
party goer: i know the harnos
owner of house: alright dude, ur in because u know the HARRRRRRRRRRNOS
