The following is an entry of a public school boy's diary. I don't understand what the last phrase "Très riping" means.
Drove to Canterbury in 3 breaks. Visisted Cathedral, very interesting. Thomas A'Beckett's blood. Très riping.
L. P. Hartley, The Go-Between
Does this phrase mean something like "very interesting"? I understand that "très" is a French word meaning "very." But though I checked several dictionaries I could not find an appropriate definition of "riping".
