Has any boss ever used this js-yaml npm bag with a blind look on his face?

there is a code:

var SexyYamlType = new jsyaml.Type ("! sexy", {
kind: "sequence",
construct: function (data) {

)
return data.map(function (string) { return "sexy " + string; });

}
});

the type here! What does sexy mean?
