I think it’s obvious to an everyday English speaking person, this is a take on a regular saying, like “costing an arm and a leg” or “sell my firstborn” or something. Though if I were this Twitter person, I would definitely avoid any metaphors involving things like this if they’ve been banned or whatever so many times.
Still, as an average person, it isn’t taken as anything but a riff on a saying.
