ODAC 

The best swim team in Virginia. Perhaps the best place you’ll ever be able to find. You’ll never want to leave.

Odac dominated everyone at senior champs. Their relay team was awesome

ODAC 

The Old Dominion Athletic Conference is an athletic organization of collegiate athletics located in the Virginia area. Made up of Lynchburg, Shenandoah, Ferrum, Washington and Lee, Randolph-Macon, bridgewater, Roanoke college, hapmden sydney, guilford, averett, Virginia Wesleyan, and Randolph college.

This conference is the most stinky, trash, and garbage conference in the whole world of division III lacrosse. Nothing good comes from here.

Brendan Mike and Tommy all played in the ODAC. They were bums.

odachi 

A sword of Japanese origin, also called a 'nodachi'. It looks like an extra long katana. The sword was notoriously difficult to make and wield and was mainly used for killing mounted cavalry troops.

I got cut in half by an odachi.

A lengthy man thingy that can cut people in half because it is very thin and sharp.
