The last Saturday before finals at Fairfield University in which thousands of students flee the overbearing pigs that run security at school and migrate to fairfield beach for a fun filled day of binge drinking, bitches, and beriut. Clam Jam includes various bands, dj's, drunk security guards and of course plenty kegs to go around.

It has recently come under the scrutiny of full time residents at fairfield beach who bought beach houses in a college town for half the price, expecting no disturbances. As much as these fun suckers try to ruin our time, clam jam will always live on.
