Unlike a solitary shank (shower and wank combined), a lamb shank is done in the presence of a sheep. Whilst this is traditionally a male lamb, at a pinch any ewe will do!
I was feeling a bitlonely last night so I had a lamb shank instead.
An annual Blackpool tradition occurring on the third Saturday of every July, wherein the locals construct a ceremonial pile of lamb shanks, leaving them out to dry in the summer heat.
"Oh yeah, me and my mates got trasheda few years ago and got arrested for disturbing the Lamb Shank Day pile."
