To be stuck means to be in a fixed position that cannot move. Examples of stuck objects include jar lids, a car in traffic, or a person. It is a noun that comes from the Old English word stician. In other contexts, stuck can mean indecisiveness.
Stuck can also refer to being extremely tired or high on crack, meth, or alcohol. This state causes one to lose concentration and feel incomprehensible. Another definition of stuck is being caught up in a lie or situation that you can’t get out of. You can tell when you’re stuck by the way you look and act.
