"Get to the chopper!" Is a funny quote from the movie Predator. Arnold has a thick accent, so it sounds more like "Get to da choppa!" It literally means that you should run to a helicopter to escape. It also can be used as a joke for immediately leaving a situation. Example: "Oh great, my ex-boyfriend just walked in. Get to da choppa!" http://knowyourmeme.com/memes/get-to-the-choppa

Get to the helicopter as fast as you can. http://www.fugly.com/media/IMAGES/Random/get-to-the-choppa.jpg
