often used for ultra-cynical young males who decide to become priests because they can't stand the idea of living with anyone other than celibate men; men who pride themselves on being homosexual as a facade for their deliberate platonic promiscuity; men who often display signs of jealousy when his other brother seminarians have managed to gain the attention of a hot girl and he hasn't.
Example 1:
Friend #1: Oh, that girl looks so good!
Friend #2: Damn, she's hot but there is no way I'd live with her.

Friend #1: You are such a Selby.

Example 2:

Man, our parish priest is a Selby, he hit on me and my daughter on the same day

Example 3:
Seminarian #1: Get off the computer! You shouldn't be talking to a girl on SKYPE. You're breaking your vow.

Seminarian#2: Don't be such a Selby dude!

A "math teacher" with 0 knowledge of anything math related. A Ms Selby is commonly refered to as "dumber than a blonde girl". If you spot a Ms Selby KILL ON SIGHT, if you do not have the proper equipment, then RUN UR FAT LITTLE ASS OUT OF THERE. As a Ms Selby is banned from most public gathering places for being too dumb, you will probably never have to worry about ever encountering one, but always, ALWAYS carry a handgun for one use and one use only... to shoot this bitch.

Scientist and philosopher extraordinaire. The Irish genius de Selby is known for positing groundbreaking theories on the natural world. Although highly controversial, he is revered and respected by many.
I find de Selby's theory of 'black air' to be highly stimulating and absurdly incorrect.
