sally forth
1. To leap out and rush forward very suddenly. We're waiting for some cover fire before we sally forth. The cat hunched behind the sofa in wait, then sallied forth to catch the mouse.
2. To set out, as on some journey, trip, excursion, etc. I spent the week getting everything in order before sallying forth to Europe. As hard as it may be, all parents should urge their children to sally forth to different parts of the country or the world after they finish grade school.
