Figurative use of 「まどから捨てる」


Yesterday, I [answered a
question](https://anime.stackexchange.com/q/40950/12985) on the Anime SE site
about a consistency between Japanese audio and English subtitles.

To summarize:

From what I could understand of the dialogue, the character in question was
saying

> 2秒いないにまどから捨ててるな。

Which I tentatively translated as

> [My argument] didn't last for two seconds before being thrown out [the
> window].

**Edit:** I have found [a clip on YouTube](https://youtu.be/_ziRxrHkg2o) of
the dialogue in question, that should hopefully not be region-locked. The
phrase is at about 0:30. It could very well be the case that I misheard what
was being said, and that my question is way off-base.

After performing a sentence search on jisho.org for similar phrases using 捨てる
as well as a cursory Google search, I couldn't find any authoritative evidence
that the phrase 「まどから捨てる」 can be used in the same figurative sense as its
translation can be in English, as in "to dismiss something completely."

My question is, was this usage of the phrase atypical, even in Japanese? Or is
it commonly known and used, and I have just been looking in the wrong places?




窓から投げ捨てる is a slangy and joking expression which basically means "to throw
away (something shitty)", "to abandon". ～を窓から投げ捨てろ is particularly common. I
would call this a set phrase, although I don't know who firstly said it. I
believe this phrase is at least 15 years old.

> Windowsマシンを窓から投げ捨てろ! Macを買え!

This is almost always used with tangible shitty products which you can
physically throw away. Usually people don't use this phrase in the sense of
議論を却下する. Maybe someone misheard something, but I don't know what's going on
without actually seeing the episode.
