1 To express vitriolic dislike of Locke and Hume and, when challenged, to respond with surliness and ill humor. ("Oh, that's just Anscombe geaching at Russsell."); ("I don't like the way he's always geaching at the moon.")
2 To quote texts without edition or page references.
3 To write complex sentences while avoiding basic proofreading.
1 Use/mention fallacy.
