Raffles Institution (RI), founded in 1823, is the oldest and most prestigious school in Singapore for pre-tertiary education. It is an independent school, providing secondary education through a boys-only Year 1-4 section and pre-university education through a co-educational Year 5-6 section. Its current campus is in Bishan. It's Sister School is Raffles Girls' School (RGS). There is a stereotype that every Rafflesian is a nerd and geek, but they are mostly all-round individuals.
Tim: Which secondary school do you want to go to?
Tom: Oh I wish to go to Raffles Institution, my PSLE score is sufficient, since their COP is only 216.
Tim: I'm afraid, my friend, that instead of 216, it is 261.
Tim: Oh no screw you :(

Ruffle is a substitute for the internet phrase ROFL. ROFL as one word sounds a bit like ruffle. It's less annoying than internet-speak acronyms and can also have multiple uses.
