When used as a noun it is the collective term for the code of honor and way of life (just like Bushido). Its origins are from Dagestan and the
father of the Smesh is considered to be the ufc fighter Khabib Nurmagamedov.
When used as a verb , smeshing is superior than smashing and always results in changing the
face of the smashed
guy. This is the highest purpose for anyone following the Smesh code.
Khabib about Conor McGregor:
"His
legacy is
money. My legacy is Smesh."
Dana White: Hey Khabib how are you?
Khabib: Hey I'm gonna smesh your
boy.
