My guess is that this is front curtain sync. The trails are positioned above the eggs, not below.
This image demonstrates the difference:

"Front curtain sync(top) fires the flash at the beginning of the exposure, then records ambient light. As a result, light streaks from the moving subject appear in front of it.
Rear curtain sync(bottom) fires the flash at the end of the exposure, after the ambient light has been recorded so the streaks trail behind the subject."

Yup, just a spur of the moment shot using the onboard flash. ISO 800, f5.6 shutter 1/40. Maybe I'll try with the rear curtain though, that'd look cool too.
