OLC 

Abbreviation for Old Lying Cunt. Used when an elderly female lies to gain attention for herself.

At Stephen's going away party for college, Grandma Byers offered to pray for him. Everyone thought that would be a nice idea, so she began: "Dear Lord, please help Stephen as he goes to college. Particularly help him with his anger problems, as we all know he starts fights, and hardly ever wins. Don't let him get beat up again. And please keep his racism in check. Don't let him use the word N-I-G-G-A-S referring to white people he doesn't like, and don't let him use the word N-I-G-G-E-R-S, for that always gets him in trouble, like it did when he used it last week..."

Grandma Byers was cut off by an angry Stephen lunging at her. "That old lying cunt doesn't know what she's talking about!!!!! Get that OLC away from me! She's not even my grandma! Who is she, anyway?"

Only Likes Children

Originating from the underground pedophile ring of the British Army on ROBLOX. OLC quickly became a gamertag for the members of said ring, quickly amounting to infamy.

He's such a nonce, obviously a member of olc.

OLCC 

A school in the North West of England, located in Lancaster. It is called Our Lady’s Catholic College but often referred to as OLCC.

The teachers there are really bad and give you detention for absolutely nothing and hands out warnings like their going out of fashion. Some of the teachers believer in nothing apart from God and insist that God is the greatest, we all know who were talking about here, it is absolutely Mr Roy Bourner.

Everything at OLCC is all about Jesus, whether you believe or don’t believe. They don’t care and they force you to pray during assemblies and mass.

The uniform at OLCC is shitty. No makeup, no skirts above the knee and certainly no trainers! No jewellery during PE and they even make you run, they don’t care about you and make you do things you don’t want to do.

The food there tastes like shit and they order all the meals and they are hot fresh! This “cafe” at our school is horrible and I wouldn’t be having anything from it ever again.

The only great thing about OLCC is that some on the teachers there are really good looking, some people may not agree with me, but I think they do.

James: They must go to OLCC, they’re a right bible basher.
