A person who is an incredible douche bag that gravitates towards even bigger douche bags with any small amount of power or standing over a group, false or real. A Spencer will coddle the balls of any perceived superior while gagging on their cock and begging for more between breathes in the hope of receiving a pat on the head or an unfounded statement that serves to validate his existence. He is an expert in pointing out the flaws of others, but seems unable to see that he sucks at life and is a complete failure when compared to anyone else. He is a snitch of epic proportions and the type of douche who will be friends with a person while simultaneously talking trash about them behind their back to anyone who will listen.
