I heard "Kick your ass on the road" in a movie. The context is that there were two people in a truck. One guy said it to the driver. From the context, I guess it probably means he had asked the driver to start off. I can't find it on the web. So, I want to ask if "Kick your ass on the road" is a common phrase? If so, what does it mean?
According to the Collins Dictionary
to punish or defeat someone
On the road is just setting the place where the defeat or the punishment may take place.
The speaker is saying to the driver that he (or maybe a third person) is going to defeat him.
(I'm going to) Kick your ass on the road
(The Bad Guy is going to) Kick your ass on the road
More context is needed to specify who is the ass-kicker but I think that the main meaning of the expression is clear
