Dicks are down

A motivational phrase uttered right before an action. Mainly used by a group of bros, to give an advanced warning signal to all that an action is about to happen, and then the reward for the action will be reaped (e.g. post work beers...).

Common in usage to "let's roll".

*near the end of a grueling work-day*
Joe: Can't wait to finish this report!
Tom: Yeah Man, dicks are down - let's finish this and go to the pub!
