Top definition
The term means to replace the middle bun of a double stacked burger, specifically a McDonald's Big Mac, with a Boston Cream. The result is a mess of calories and delicious (not really at all) creamy, meaty goodness
Yo guy, let's hit up McDonalds and Tim Hortons and make ourselves some Boston Big Macs
