the gayest dorm on stanford campus. full of hypocrites, hippies, douchebags, and pussies. the bitches can't afford to be stuck-up because they're ugly as hell, yet somehow they are. the guys are guys in so far as they have empty sacks where their balls used to be. the most unreal place on the face of the earth.

synonyms: film actors guild of america (f.a.g.), george michael's bedsheets, hell, brokeback.
1. fuck, my ass hurts. i wish i had used more lube when i was in arroyo last night.

Top Definition
Arroyo cactus (Catacallis Covillei) is a member of the cactaceae, characterized by dusty brown skin and bright lavender flowers. Found in desert regions of North and Central America, the arroyo cactus is most likely found in dry creeks, washes with severe erosion.

Known also as Washbaby, Dog Ditch Dweller, Dirt Trapper.

Unlike its cousin the barrel cactus, the arroyo is a non fruit producing cacti, who's bloom serve purely for ornamentation.

Due to over cultivation of land in it's principle growing areas, the Arroyo has suffered a dramatic decline in the last century. Botanists from the Lomax-Kurshberg Institute are attempting to produce healthy Arroyo specimens within artificial conditions.
