Ok. Just gonna pin this comment. Be very careful about jokes that could be interpreted as threats of violence or encouragements of violence. Lemmys rules are quite strict on this issue. Please consider this before posting your comments. Thank you in advance.
Always seemed like such a strange word. Like, it's such a common thing that English needed a word that specifically means to throw someone out a window?
Fenestra is the latin word for window.
Similar words are used in some latin languages as Italian, catalán or Galician.
I don't think it would be much used in central Europe, maybe in Romanian, as it also derivated from latin. But I don't think that would be the case for Germanic or slavic languages.
Edit: just looked it up, seems like some Germanic languages also have the same Latin root for window.
Why metaphorically? Invite him to one of those Western town amusement parks where you can have a fake bar fight and throw him through a sugar glass window.
