A party which involves more "Scrumping" then alcohol, and drugs. This usually occurs when there are more women, then men. Only certain circumstances could involve more men, then women. Can occur anywhere, or anyplace at any given moment. Only if basic party needs are aquired (like alcohol, drugs, and/or entertainment) can a Scrump Fest occur.
Person#1: Yo, did you go to that party on St. Patricks Day?
Person#2: Hell yea, the party was a total "Scrump Fest."
