Jambuster

When you're going hard in the back and you start to blow it and leave half inside and the rest caked on the buns.

You creme fill the bun and layer the icing on the bun, thus being a jambuster.

From Manitoba, Canada, it means a Jelly filled donut.

The filling squirted out, as he ate the Jambuster.
