The cowboy emoji is used to convey forced cheer in the face of disaster. It is the visual version of "smiling through pain." Teens use it to react to bad news or awkward situations. Not concerning; it is often self-aware humour about being overwhelmed. If it appears very often, gentle check-in for stress. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in.
