When I worked for Disney I learned out to abv. everything. and i mean EVERYTHING... its like talking a different language. So I was just going to see if anyone could tell what these mean? and if you do know most reply, and after people reply DON"T LOOK at other peoples answers if you are wanting to test yourslef... A lot of these are ones that Cast Memers use on a regular basis, so dont pressure yourself to much if you can't figure it out! And if you have any you would like to add feel free, and i will also see if i can get them! and some may have more than one so i will put a (2) beside it, you can answer one of both if you would like! some may also have to do with other parks world wide!
