2. To get messed up really bad.
3. To send off.
An other example would be when you're the passenger of a car and the driver almost hits the curve, you yell "DEPLOY!"
(These are just yelled with nothing too special.)
2. For example after you have packed a bowl and knock it over, you would then say, "deploy"
(This is said in a medium tone and when you get to the "oy" part is starts to trail off like--> DEplooyyyyy.......)
3. This would be a case when you would also say deploy, when you're about to plummet, or drop in. So just before you go you'd say, "deploy"
(This is said short and punctional.)
