The new trend, or at least for San Francisco urban hipsters, has moved from cow tipping to Smart car tipping.

KNTV-TV in San Jose reports that a witness was out smoking around 1:00 a.m. on Monday, when he saw about six or eight guys in hoodies run up to a Smart car and tip it over.

Police reports show that there were four other cars reported tipped over that night.

It's a funny sounding concept, but each tipping costs thousands of dollars in damage.

Police say if they catch the Smart car tippers they will be facing felony charges.
