"Contact, wait out" is a term military personel use over the radio to report enemy sightings/attacks. "Contact" means that the enemy has been identified or that you have already been attacked. "wait" means that you have no time to explain the situation right now. "out" means that you are about to end transmission and will call back later.

Lieutenant: Holy shit, call it in!
