The name of a house which hosts parties for college students at Cal Poly in San Luis Obispo. The house itself is not spectacular and the parties are nothing of legendary value. Nevertheless, it’s events are pretty much open-invite which attracts newer students to a fun environment.

Bro 1: Hey brodid you see the flier for the Sendagon party tonight?
A Sentagon is a sentar and dragon mix that has multiple personality disorder. It thinks it is a dog and a dolphin. It likes to live in fires because it thinks it is hot. At times he likes to live in the ocean and be free with other sea animals and use the dolphin call, when he thinks he is a dolphin.
