look up any word, like fleek:
 
1.
That turn you make when your light's been red forever and there is no one around, so you turn right* onto the cross street and quickly make a u-turn, then turn right back onto the street you were just on, now past the light. Named for the shape of its path's resemblence to the upper-case Omega symbol Ω

*for places where you drive on the right side of the road. All maneuvers are reversed in places where you drive on the left side of the road
I was gonna be late because of that long light at Topanga Canyon Blvd. but i saw my chance and did the old omega turn, and off i was to my appointment, right on time!
