riston 

A loveable, yet gangly office creature who stopped maturing after university. This has led to a life of intramural sports, socks with sandals, and a propensity for much younger females, and useless trivia. Quick witted, and dangerous when cornered.

He was so friendly until I cornered him, then he became such a Riston. Yikes!
