slang for real good felatio; derived from the scene in the Coneheads movie when Beldar was taken back to his home planet and was sentenced to narfel the garthob (fight a huge,ugly monster to the death).
Aurora Snow can narfel the SHIT out of a garthob!!!!
My friends and I picked up this phrase from the Coneheads movie in the early 90's. We adapted it to make fun of the guyshooking up with less than perfect girls out at the clubs or where ever.
