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 bit lonely 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 trashed a few years ago and got arrested for disturbing the Lamb Shank Daypile."
