look up any word, like ethered:
Grawl - the sweaty substance that accumulates in the crevice between one's inner thigh and nutsack
Lawl - Laughing aloud whilst lisping

A secret underground sign of greeting among those in the know. Believed to have originated by a student at WNEC.
Mike: "Heyo!"

Dan: "Grawl lawl lawl"

Mike: "Grawl lawl lawl!"
