An action by one male to another male friend which violates understood social expectations, especially where the transgressor obtains a slight advantage in comparison with a relatively large inconvenience imposed upon the aggrieved party.
It was a dick move when Tom encouraged several dancers at the strip club to order drinks, then left his friend Bill to pick up the tab.

Tom and Bill were both interested in the same girl at the bar; when Tom falsely insinuated to the girl that Bill had erectile dysfunction, that was a dick move.
