Smelly Nelson
an unofficial wrestling maneuver of unknown origins that consists of one person restraining another by positioning their face in your armpit. Widely considered to be one of the best demoralizing acts that can be performed on a rowdy acquaintance or a younger sibling. The "smelly nelson" could be placed in a similar category as other demoralizing acts such as wedgies, noogies, swirlies, monkey bites, charlie horses, and purple nurples.
My younger brother Jack tattled on me for sneaking beers out of the fridge so i promptly put him in a smelly nelson to teach him a lesson.
