a lamb kebab bought in the london district defined by zone one and zone two of the london underground.
The word comes from the remarkable resemblance between an elephants leg and the universally accepted sign for a kebab shop in central london and the actual rolls of lamb meat on rotating skewers inside the shops.
a) you want to go for an elephant leg
b) there's an elephant leg shop on the high street.
An oversized marijuana cigarette. A big fat joint.
Dude, we're gonna get totally ripped if we smoke this elephant leg.
