fagytrés

Could you please provide a bit more context for the term "fagytrés"? I’m not aware of a widely recognized definition by that name. If you mean a real concept in Hungarian (for example, something related to frozen pastries or a geological/ice-related term), I can write a concise, neutral wiki-style article. If you’d like, I can also create a fictional, neutral encyclopedia entry for "fagytrés" as a invented concept. Which would you prefer?
