Acronym for the Royal Kennebecasis Adventurers Society. The acronym is meant to be pronounced 'ruckus' which fits with the society's mantra of having adventure which provides a disturbance or commotion.
Did you hear about the latest RKAS adventure? I heard they climbed a cliff-side looking for pirate gold.

A school where there is a dean who likes to sell cookies to kids, check girls out, stand on a table, spit on a microphone all day and he likes the assistant dean.
Girl: Why does the dean of my school always look at my ass and offer me cookies?
Dude: Maybe that school is an RKA.
