Yeah I know it's not bleeding edge marckee, but I did some googling and surprisingly not been mentioned here yet.
It seems anyone who I once went to school with an am still friends with on Facebook (a rapidly shrinking venn diagram overlap) is posting videos of themselves necking a pint then nominating 3 other people to do create a similar video of their own within 48 hours.
So far the machismobellendia on display has included:
1. Someone doing the plank while necking a can of Strongbow poured into a pint glass.
2. Someone cycling on an exercise bike before emptying a can of Miller into a beaker then using his bicep to cradle it while he downed it.
3. Someone necking a pint, pissing it out back into the pint glass, then necking it again.
