A religion practiced by millions worldwide
The core beliefs of excuse-ism are

1. I am the best and every time evidence shows otherwise it is somehow a mistake

2. I am never at fault for anything bad that happened even if I actually did it.

3. With a lot of help I can be as good as anyone who needs no help at all.

Due to it's Narcissistic nature, Excusism can not be taught by preachers, it is usually passed on from parent to child through heredity or spoiling.
Excuse-ism practicer fails out of his 3rd college his/her response will be "I had a rough childhood, I should be allowed to practice medicine because my ADHD and alcoholism are not my fault, even though they will cause the deaths of many treatable patients"

A strange condition that affects only the male species causing them to only call a female with the use of fiber optics ONLY after the SUN sets.
Contrairy to popular belief these types of men cannot be repelled with "crosses" and "garlic", but have been known to be wounded by the usage of soap and water (whether holy or plain). There is question as to whether or not this species is affected by sunlight, due to the fact no one has been able to capture one and find out. Studies have confirmed the fact that when a female recieves a phone call by these types of men they ALL seem to want the SAME thing.

A word commonlly associated with married men, or men who are just "NO DAMN GOOD".
Darnell only seems to call after 11 o'clock at night, I wonder if he has VAMPIRE-ISM.
