A screech point is an exclamation point at the end of a sentence. Something a person on occasion screeches when writing, "!', or "!!", which is a double screech point!! As you can see, it quickly becomes meaningless !!!! And so, "screech point" should be used sparingly. And so, its rarity!
The sun in the late afternoon water appeared in the West as an inverted screech point, as i shielded my eyes with my hand!
