Two wheeler, four wheeler

Time Out Mumbai keeps an ear open for city slang. Here's a sample from the October 22 issue:

Two wheeler, four wheeler: Culinary euphemisms used by Gujaratis and members of other traditionally vegetarian communities when they succumb to the pleasures of the flesh and order up dishes made with the bipedal chicken or the quadrupedal goat.
Example: When we went to Bade Miyan yesterday, we couldn't decide whether (sic) to have between two wheeler or four wheeler, so we ordered both.
