The mating ritual of Aussie Bogans, who in order to demonstrate their penis length/girth and demonstrate their readiness and desire to mate with other Bogans, must chug a full beer on video, and then nominate another Bogan to do the same.
Most commonly practiced before a night taking the Commo out to Chapel Street, downing a slab at Bazza's place, or hitting the drags at Dandy.
"Tommo totes just chugged a Vic, and Neknominated that dog cunt Robbo".
"The Ranga got Neknominated, the weak dog only downed a double black!".
One of the woolly little sheep following the neknominate trend "nominates" someone whilst they are filming their own incredibly lame video of them chugging something disgusting, and the person they've chosen HAS to complete a video, unless of course they aren't as desperate to be socially accepted by a bunch of drunken buffoons as said nominator...
"I was Barry's neknomination, better make a well original video of me pouring a drink and then drinking it in a onesie"
Someone who is neknominated has 24 hours after nomination to mix together a variety of spirits (and whatever else they deem worthy/disgusting/difficult) and post a video of chugging it in one go. After necking your drink you then nominate at least one other person.
Jane: "Thanks John for the nomination, I've got blueberry vodka, Jager, regular vodka, wine, absinthe, cider, OJ, salt, sugar, cinnamon and milk in here...." *drinks the mixture* "I now neknominate Bob and Sally!"
Nickname given to bales of marijuana thrown overboard or out of airplanes. Origin is reportedly from members of the US Coast Guard in the area of Southern Florida.
"Base we've got some square groupers floating outside of Miami harbor."
