I saw something similar at NPF bassets pole last year sometime. I think they called it 'the birthday run'
Some chap admitted to it being his birthday whilst playing a punter game with about thirty other lads so the marshall lined us all up and we basically laced the crap out of him whilst he ran along the line
Birthday run, stag run or death row its called at our site.
Done it once on my Birthday, was fully clothed though.
After the first 1 or 2 hits, its not so bad
