Tom: Hey, what happened to my french fries? I go to the restroom and I come back to find them almost gone?
Chris: Yeah, when you left I saw John snake a handful of them. He just laughed and walked away.
Carol: You're never going to believe what happened yesterday. I was at the mall waiting for this car that was backing out because I wanted the parking space. I had my turn signal on so everyone would know that I was waiting for that space. Then, right before I could pull into the space, this other car quickly pulled in and snaked the parking spot that I had been waiting for.
Barbara: No way! That's crazy!
Meaning: "To snake something" means "To steal" or "To take something wrongly."
It is an idiom that has an origin in surfing culture. When a surfer is waiting for a wave and he/she is in the proper position to take the wave but another surfer "steals" the wave, they say that the other surfer "snaked the wave."
