Top Definition
A micro-organism that resides in the adrenal gland. This tiny organism is there to control the adrenaline in the body. While these are vital parts of the body, phyglocelyn levels have been known to drop in about 4% of all documented cases of hyper-activity. As the levels of phyglocelyn drop, more adrenaline is able to escape from the adrenal gland, causing a body to become overly excited and energectic. In these cases, medication is available by doctor prescription to bring phyglocelyn levels closer to normal.
Most obvious symptom of low phyglocelyn levels: excessive energy.
