In 50-60s it was a slang word, meaning any woman who was a student on a predominantly male campus.

The term is almost not used except for in association with porn, it allows someone searching for porn to use a search term that would more likely produce a porn specific result.

For example compare the search results for “cute college girlvs “cute coed”

Co$ stands for the Church of Scientology.

"The Church of Scientology is a vicious and dangerous cult that masquerades as a religion. Its purpose is to make money. It practices a variety of mind-control techniques on people lured into its midst to gain control over their money and their lives. Its aim is to take from them every penny that they have and can ever borrow and to also enslave them to further its wicked ends.

It was started in the 1950s by a science fiction writer named L. Ron Hubbard in fulfilment to his declared aim to start a religion to make money. It is an offshoot to a method of psychotherapy he concocted from various sources which he named 'Dianetics'. Dianetics is a form of regression therapy. It was then further expanded to appear more like a religion in order to enjoy tax benefits. He called it 'Scientology'.

Scientology is a confused concoction of crackpot, dangerously applied psychotherapy, oversimplified, idiotic and inapplicable rules and ideas and science-fiction drivel that is presented to its members (at the 'advanced' levels) as profound spiritual truth." --

Coed is short for coeducational. This means, both men and women can play on the same team.
Coeducation is the integrated education of men and women at the same school facilities; co-ed is a shortened adjectival form of co-educational.

"Coed" is an informal (and increasingly archaic) term for a female student attending such a college or university. Before the 1960's, most institutions of higher education restricted their enrollment to a single sex.
Some coeducational sports are:
Indoor Soccer, Volleyball, Floor Hockey, Street Hockey, Broomball, Flag Football, Trench, Ultimate Frisbee, Badminton and Doubles Tennis (Teams may consist of two players of the same sex, or one of each sex).
